Unbalanced weapons? Like you can't defeat rifles with smg's? Haha. Unbalanced maps, sure, if you play the cs_ maps or de_dust. I'm not up to date on CS:Source, so I don't know which de_ maps are in just yet. Most of the ones used for competitive play in 1.6 like dust2, inferno, train, nuke, and cpl_mill are very well balanced. Hostage AI hasn't been important to me the last 3 years of CS play. What makes CS better? Smoothness, customizability, quick gameplay, accuracy, balance of skill and strategy, massive community, basis in reality. I'm betting all the haters in here are noobs that have only played a few public games, and probably aren't very highly skilled. It takes a lot more skill to use an AK47 in CS than spray someone with plasma rifle fire and unload an smg. Part of the appeal of both I guess.
