Should I go 35F or 35M?

You've already got a few answers, with a lot of info. So I'll try not to cover what has been covered. I was a 35M for about 10 years (now retired). During that 10 years, I spent about 5 in a 35F job, because they were short Foxes. There are always exceptions, based in the individual, the unit, and the missing, but GENERALLY speaking 35Ms will get out and about more than 35Fs. However, 35Ms for the most part only exist in MI units, whereas 35Fs exist in pretty much all units in the Army. (35Ms are often attached out to combat arms units for certain missions or even full deployments, which enables them to get out and about, but they are assigned to MI units.). 35Ms generally are 65/35 brains/brawn ratio - gotta be smart, able to think on your feet, able to see the big picture, and able to see where the wholes in the big picture are so you can go fill them. Also have to be able to keep up with the combat arms folks if you do get to go out on patrol. 35Fs are more like 80/20 or 85/15 brains/brawn - gotta be able to not only see the big picture and identify the holes, but also figure out what PROBABLY goes in the holes, as well as how to conclusively fill the gaps beyond conjecture. Also need to maintain basic Soldier fitness. 35M is more social and psychological, 35F is more cerebral.
Of course, you could sign up for 35 M and end up doing the 35F job anyway, like I did - or sign up for 35F and be doing HUMINT analysis (which is technically a 35M job, even though neither the Foxes or the Mike's usually want to admit it).
I hope that helps compare and contrast the two a little bit better for you, so you can make a (little bit more) informed decision.

First off, kudos to you for deciding to serve your country. Now I see that you have gotten bombarded with several answers more so, it seems answers that focus more on changing your mind due to personal experience. That is fine, however, to address your question it is all a matter of who you are as a person. While all of the intelligence disciplines are important and some do carry a heavy weight towards the future there will always be humans around to talk with and gain information from. In order to make that choice I would advise that you take some serious time to weigh and consider your own personality. First, how do you feel about interacting with new people. If you have trouble making friends or talking with strangers then 35M could be a bad choice. Although, I have met a few introverted 35M's they are the exception, not the rule. Second, the 35M field attracts those with dominant personalities, if you struggle in dealing with those kinds of individuals then 35M might not be a great fit. Third, 35M is a field that requires a lot of emotional stability, if you struggle controlling your own emotions when people push your buttons then you might struggle with the school which will challenge your ability to keep your wits about you while maintaining focus on the task at hand. While this list could go on about the negatives and personality quirks that help with career fit, think about it this way, could you do the job your recruiter is doing and perform well?

While much of what I have covered is negative in nature from what you are saying about your skill set points to 35F, that is not a bad skill set to have in the 35M field. It is a blessing especially if your mind works quickly in analyzing facts and data. That will help leaps and bounds in the planning and preparation that goes hand in hand with the job. Additionally the skill set taught in that course is foundationally exceptional for many civilian jobs which can be easily translated into career opportunities if you decide to stay reserves and look for a steady job. However, if you think you might transition to active duty then advancement might be a challenge, when I left the service active duty was crowded and promotions were slower moving.

I hope this helps to answer your question to a reasonable degree. Good luck with making your prospective career choice.

Neither. If you get into the MI world, 35N. Is the way to go. Too many reasons to list them all. But, I’ll knock out a few of the big ones. First, SIGINT and cyber is the future, and it’s already here. It’s why CYBERCOM is being elevated to its own unified combatant command. (ie:CENTCOM, SOCOM, etc). Second, of all your intel shops, the Novembers are at top of the food chain. If you wash out of 35N school (at Goodfellow AFB) you’ll get reclassed to another 35 series and sent to Huachuca. But if you wash out of any of those, you’ll probably get reclassed to needs of the Army. Make sense? As for DLI. I’m not sure how it works in the reserves. But for active big Army, if you don’t get it in your enlistment contract, DLI is like any other school. It’s a DLAB and 4187 away. Your original question didn’t ask about a language, so I won’t go in depth about Monterey.

Also, just some good NCO advice...you’re not even in..the..Army..yet. You have no idea if you want to be deployed, let alone stuck on the FOB. Get through basic training/AIT/unit time first before deciding just how much time outside the wire you’re ready for. That said, as a fox, for the most part, tactical options are limited. As a 35F, get ready for a lot of data compilation and power points. Mikes have a few more options, but to be honest, the most tactical work that a lot of 35m’s have done is gate guard or tower duty. There are definitely some Zero dark thirty types out there, but they are very few and far between.
35N has excellent tactical opportunities for all ranks in both conventional and special operations worlds. Don’t get me wrong, there are November’s that never see the light of day because they’re plugged in to a computer 28 hours a day. But on the other hand, as a November, if you prove you have the ability, you’ll have more opportunities to more insane things than you can currently imagine. And back to DLI for a moment, if you’re a November with a language, well the sky is the limit.

In my many years in the Army, I had a lot of 35 series soldiers ask, “hey SGT, I messed up, and should have picked N instead of (usually M, F, G). Can I reclass?” And after I’d tell them to go talk to their first line supervisor to get the ball rolling, I’d always ask my soldiers how many wished they had picked a different MOS when they joined. Honestly, I never had a soldier say they did. Not because I was the greatest NCO. It’s because it’s genuinely a ridiculously challenging and interesting job. Soldiers across the Army, even in MI, beg to reclass to 35N. 35N’s don’t ask to reclass out.

I got long winded. To nutshell, 35N is a superior choice to F and M, especially if one of your main considerations is tactical job opportunities.
