Wannabe,
First of all, I hope you have checked out

Just like everyone else has said, choose the mission. I chose Gun's for a very specific reason and didn't look back.
I LOVED being the guy who layed down the hate and discontent when some sh!tbag threatened my bud's.
Do NOT fall into the trap that most do and criticize the other airframes once you pick your path. Ask them about their mission and learn their mission too, you'll be working together if you are going to carry on the tradition of Army Aviation. A good precursor to this is the 'Common Area' in WOC school. (you'll understand)
You'll see the penile-envy syndrome big time in the real army(outside of TRADOC). But, when you go somewhere for real and you find yourself flying real-live missions with hawks, hooks, or scooters..you'll grow to realize the tough job they do and respect them because each airframe has great folks and they bring an awesome piece of the puzzle to the game. I know, I know, it sounds corny but it will click out in bum fork egypt some day when you see it all come together. That is the thing that makes the poor QOL worth it.
I chose Guns because I talked to a former attack dude who explained how all of the armament systems worked and the different types of warheads, weapons, and engagement techniques. WOW!!! that stuff is COOL!!!!!
I love the other missions and airframes but, I didn't want to hover down into a hot LZ and not be able to hurt the schmucks that were shootin at me. I also wanted to make things go BOOM! You don't get alot of ammo in the peace time army but, when you send missiles down range in the middle of the night and see the explosions, it's cool. Doing running and diving fire with rockets was my fave. The 30 mm was an extreme hoot also. When practicing firing it on or off axis with live rounds (exploding) I came to feel that I could honestly protect my CPG very well in most situations.
I flew the 'A' model Apache and absolutely enjoyed every flight (sans checkrides) but I have very good friends who flew the others and they had the same experience in their respective airframes.
Bottom line...
Work really hard in flight school because you will be on a two way live fire range some day- just the way things are. Don't be a hero. Do your job, nothing more, nothing less. Not trying to be 'over the top', it's the truth in this day and age.
With respect to what aircraft you fly, look around, pick one but realize this, and I promise you'll hear it again....
"Whatever AQC you end up in,make the most of it. Each airframe has it's benefits and problems."
The sorriest guys I saw were the ones that always whined about what airframe they wound up with. They are not part of the team and that is a fate worse than death.
Also,
It's not so much about the physical aircraft you fly... It's more about the guys and girls you fly with and for. Remember that more than anything. It will make sense in three or four years. Trust me. It's the PEOPLE, not the machines that keep me up till the wee hours of the morning.
Good Luck Brother.... work hard. The people on the ground will expect it!
AND THEY DESERVE IT!!!
