Depends on what you're looking for. If you're looking for a particular game, look at what it's available on (i.e. if it's PC-only, then you have to go PC).
If your games are on multiple platforms, or you're looking at multiple games, then again look at what platforms they're available on. If game #1 is available on platforms A to E, game #2 is only available on platforms B through D, and game #3 is only available on platforms A, C & D...then your only options are platforms C & D (the ones that run all 3 games).
Beyond that, consider the following:
-- Console games tend to be stabler (no guarantee, especially in today's connected console world where they can push patches out to the console's hard drive), but only because the developers only have a small number of hardware configurations they have to worry about supporting, not because the developers are that much more talented (they aren't) or that there's superior hardware in the consoles (there isn't).
-- PC games have more flexibility with the graphics & settings. Unless you have some really crappy developer studio (*cough* Bethesda *cough*) that claims that you need the absolute bleeding edge of technology just to meet "minimum" standards, there will be a wide range of display & sound capabilities with the PC version of a game because the range of hardware is much more vast. Unlike with PCs, consoles not only have standardized hardware in them, it's not bleeding-edge standardized; the technology is usually new enough to make it superior to the previous generation, but old enough that most of the kinks have been worked out. it's one thing for Gigabyte to have a small handful of GPUs RMA'd for defects; it's another for Sony to have a bunch of complete consoles RMA'd because the GPUs were faulty.
