You are completely missing the point : nobody is saying that CS is perfect and TF crappy as hell.
It’s just that some features of CS are more user-friendly. So far, I’ve not seen any major game glitch in CS that becomes painfull over time. Meanwhile, there are many of them in TF, still not corrected 6 month after release (rail crossings, terrain alignment, 20mn rule, map editor, etc …) and without any feedback from devs.
