The problem with CS:S is that it doesn't have the gameplay aspects to be tactical, but the game is played out to be (one-life, no respawn). It's more suited to be a Deathmatch, but it doesn't actually have a DM mode.
I loved the TacticalGamer server because they did more simulation, and the games were more intense due to players acting like mature adults, and not screaming "loving NEWB AWP UR GQAY UR MOM SUKS CAWKS LGODJFEFJNUEFKFE HURRRR".
