Which guns should I get?

So... I wasted all my ZP trying to get the halloween guns and the AK knife and got nothing to show for it.

I have 143k GP

Im thinking about buying 3 gp guns
I currently have the micro galil, winchester scope, awm, deagle, and usp (this was my first account, and i decided to not sell the galil)

im thinking about getting 3 guns out of the bottom list...
AK47
QBZ
AUG
RPK
G36K
XM8
TAR
SCAR-H (no i wont get s-lite)

which 3 should I get?
im 90% sure Im getting the AK already since i love the way it feels

Also, I like to do small bursts, but I can single shot
I love the AUG's accuracy, but the reload kills it for me
I'm not so sure about the feeling of the TAR, but its not bad
The Scar-H is the same with the AUG, accurate, but bad reload
The xm8 has a decent feel, but feels too light, if that makes any sense
I love the g36k scope and punch
The RPK is up there cuz its the RPK
and I've heard great things about the QBZ, but I havent used it enough to get any solid thoughts about it

Any (good) comments would be appreciated
