1.6 is for the most experienced, but its population is slowly hemorrhaging. Source is less random than 1.6 and still has people playing it. Global Offensive is the easiest to get into and the hitboxes and stuff is a lot more refined. It's also generally agreed upon that in CS: GO, the player skill is lower compared to previous Counter-Strike iterations.
EDIT: forgot answer
Global Offensive, because it's new and all.
