If you had a choice, which uniform pattern/style would you want to wear?

Can someone please enlighten me as to how the black leather boots are functionally better than the current tan boots in use?  And how we would all be so much better if we went back to them?

I am really not addressing the question but I don't want Congress having to do with anything to do with what service members where to work or to the combat zone. 

I would say lets go with the Marines uniform, but allow the army to have modifications. Like allow us to have the unit patch, and the combat patch under the American Flag, and our name plates horizontal and not at an angle.

Everyone is all Multicam! ... MARPAT! ... Next cool guy operator pattern! And I'm all "can I just get my one piece flight suit back please?" Because those were fantastic.
Now for the real discussion:
I think I am going to have the dissenting opinion on this. I understand the budgetary constraints, the "financial crisis" that we are in now and how much sense (cents?) it would make to have a common uniform to "save taxpayers money." However, I like that fact that I can look at a uniform and see Marine, Navy, Air Force versus trying to have to guess by haircuts, rolled up sleeves and headgear. A few years back the whole joint base concept came into being and I started to see more "sister services" folks walking around on Army installations (perhaps it was because of where I was stationed at the time) so it was easier for me to differentiate between who was who.
Why do I believe all of this is important? Well besides tradition and individuality of each service, the regulations that each service has on wear and appearance of uniforms differs between branches. Sleeves rolled/un-rolled, boots bloused/un-bloused etc. There is uniformity without uniformity.
Who is to say once we have the same service work uniforms they won't push for the same service dress uniforms for the same reasons? Marines with Navy dress uniforms, Army with Air force dress uniforms. Camo patterns are the tip of the iceberg, just the tip...

I understand that Congress want a our military base more of a joint force but the differences in our forces is what makes us special. The uniform is the first think you see. The ACU is the worst uniform that are out they wear put to fast for one and second before the mulitcam you were wearing Gray in a desert environment. By far the Multicam has been the best uniform out there. Does well in the environment that we as a force are operating in. Also seems to work well in a jungle environment also.

I'm hoping someone here can help explain the historical (recent) context to me.  This is what I am tracking; please correct me if I am mistaken.  During the 90s, the services generally had a common field uniform.  In the early 2000s, we deploy multiple service branches to Iraq (for example), yet they utilize very different field uniforms...some of which clearly not meeting the spirit/intent of camouflage.  Why did this departure from a common uniform happen?  If we had multiple service branches in Iraq at the same time, then why were they not wearing the best-in-class camo uniform?  How did this decision come about?  ** Note: please provide some facts if you can, instead of just putting senior leaders on blast with no facts. **

A common uniform would be great.  I remember in the late 90's, I was assigned to an Joint unit and we all wore the Woodland BDU's as a common uniform, and we updated patches and identification accordingly.  It worked out well, but that was before a lot of the digital patterns came out.  

BDUs I hate that joint commands now look like multinational commands. Also most of these "battle" uniforms are worn exclusively in garrison so wouldn't it be cheaper to wear flat OD green BDUs like the Israelis? It would save a ton of money and either way you aren't going to blend into your office.

Who really cares (except the uniform makers), it will change again in a very short time.

The one I don't have to purchase.
