(colt's shot grouping is smaller with silencer, on CS, but not CZ or the Xbox Version)
I like the MP5 and the CT pistol (forgot the name, I dont have the HD space for CS, so ive been on Xbox...) thing. Why? They're ****ing cheap and I can kick ass with them. The MP5 is powerful and accurate enough for my liking. I combine it with that pistol CT's start with, and kick ass. Silencer makes is deadly silent at range, and it's easy to pick up headshots with it. I can pick off 4+ a round with it alone ^^. And, because it costs next to nothing, I can live pistol/mp5 and later on buy AWP's and Colts for my entire team.
As a terrorist, I stick to AK, because its also cheap and a bit better than the MP5. I always later go to a bullpup/AUG, since I just tend to be lucky with them noscope. Once I killed the entire team with it, 16v16 ^^;;
I also always keep an HE grenade on me, i'm damn good at throwing those. They're always worth the lucky 4-8 kills with one toss that ya get every-so-often ^^
As a moral, I stay away from AWP's and deagles. Besides, I kill WAY more with a scout (hell, I can shoot without everyone and their grandma knowing where I am) because RiX uses them, and RiX sucks bawls.
My 2.3cents?
