I am prior Army, and can sit here and preach to you about the Army all day, but all branches have something that the others dont...it is up to you to decide which one fits your life-style better.
I saw a recruiter for every branch, and in the end, I chose the Army because I was garanteed the job I wanted (provided I passed all of the schooling for it). I got a 92 (of a possible 99) on my ASVAB which pretty much allowed me to enter into any job I wanted, so that made it a bit easier.
Airforce tried to sell me on quality of life, Marines tried to sell me on the "cool factor" i.e. the "chicks dig Marines, and we are better than everyone else" mentality. The Navy tried to sell me on the whole traveling the world aspect, and the Coast Guard guy was up front (to my knowledge) but I just didnt really like what they had to offer.
They all had certain benefits that were nice, but I chose the Army because of what they offered. I got an enlistment bonus, and job of choice (Psychological Operations Specialist) which included 6 months of language school (Arabic) and Airborne school. I did my research and found that the active duty PSYOP group was split into 6 battalions at the time and each covered different regions of the world(Central and South America, Europe, Asia, Africa, middle east, and a tactical battalion) which allowed me to get some traveling. I ofcourse ended up in the tactical batallion which kept me deployed to Iraq both times, but I dont regret it one bit.
Any way you choose will be awesome. They all have great things about them, but like I said, it is up to you to decide which you like better. All I recommend is that you think about your future when you decide. Which one will offer you the best chance of having a good civilian job if you decide to get out after your enlistment is up? the skills of a glorified killing machine arent what employers are looking for these days. Technical positions are becoming more in demand, especially computer related fields.
Just think about it, and do your homework before you sign that dotted line.
