In my opinion, console games is better.
The reason is simple, console had less problem to worry about compared to a PC games, except if you had the first edition of Xbox 360 (RROD, disc scratches). That thing can be a pain in the ***.
Gaming PC cost not only more money (except for Xbox 360 in a long term, annual fee for Xbox LIVE), but also cost a lot of your time, which will be spent on maintaining PC. On software alone, (based on Windows OS) you need a lot of stuff. Anti-virus, firewall, registry fix, junk files cleaning, scanning disk for errors, disk defragmentation, Windows update, drivers, DirectX... it's a long list. Heck, if you followed Microsoft advice, you need to reformatted your PC every 6 months... Which means you have to do the 'long list' again every 6 months.
So yeah... I think that's it... Console is better for gaming, in MY opinion.
