Alot of those games have compatibility issues with newer operating systems and counting emulation renders the debate meaningless; consoles can be modded to run emulators as well. As many thousands of hours I've spent across Counter-Strike and Dota, I'll take the PS1 + PS2 library over my PC games any day of the week.
I swear, I can never tell when it's okay for us to count legacy titles in these threads.
I stuck with the PS3 because Sony did what gamers so often clamor for: invest in new IP. It resulted in the two universally-rated best games of the generation (The Last of Us and Uncharted 2), others that were incredibly experimental and ambitious (Heavy Rain and Little Big Planet), and more that were just plain fun (Infamous and Motorstorm). Every "Top 360 Games" list I've seen is dominated by games that are also on PS3. And last generation is the first time I did not buy a Nintendo system as my second console. I probably spent the most time between the DS and PSP but the former's library is far too derivative to be in the running while the latter never differentiated itself enough with its own identity.
