CSGO or CSS

Which is more of a true Valve classic that will be in the books

CS:GO will be for sure.
CSS was short lived and still remains the middle played game between the CS 1.6 and the CS:GO
CSS was basically a jumping board.

CSS - better memories more fun gamemodes, CSGO - more competitive, more addicting and more rage, toxic shit in your life, but it's also fun for a couple of hours, when you start losing and raging.
