If I plan to go to college to commission through ROTC, would you recommend I deploy before college (for enlisted experience)?

Deployments do not suddenly grant you some kind of mysterious treasure trove of experience and knowledge. If you happen to deploy, good on you; have fun and stay alive. If you don't happen to deploy, so be it, pal. I'll let you in on a little trade secret: there aren't many butter bars that show up with deployment patches anyways... Keep that to yourself though.
If you want to go green to gold then do it. Don't postpone your education and development because of some imagined importance surrounding deploying. Believe me when I say that there will always be another opportunity to go and deal with that suckfest after you come back as a 2LT.

Experience would be helpful, but I personally wouldn't recommend unnecessarily delaying college just for that reason.

I agree with LTC Kevin B. . I also enlisted in the National Guard prior to attending ROTC. The order of merit list which determines your component and branch is based off of GPA, leadership potential, APFT score, and voluntary contributions to the organization via extracurricular activities, not prior-service. You would be better off in my opinion contracting with ROTC immediately and participating in the Simultaneous Membership Program (SMP). With SMP, you participate in both the Guard and your college's ROTC program at the same time. During this two to four year course, you'll be paired with and mentored by a unit officer. In some instances you will be the acting platoon leader of a real platoon. More information on this program can be found at:
