PCs have better controls, higher skill ceiling, and higher level competition so if you want that go with PC.
If you want an example of the superior level of player movement on PC shooters look at

like how you use QL for an example lol thats old school, but deff will show the precision
OT:
I prefer PC over any console for FPS games; why?
- Better control and precision overall
- depending on your rig, PC can blow away any console, graphics & performance wise (no exaggeration, for eg. http://www.youtube.com/watch?v=shZzYkpl5Nk or http://www.youtube.com/watch?v=BkZp2c_vzNY, make sure to watch in 1080p)
- Competitiveness; PC has a larger competitive scene for the most part because most is done over the internet, LAN's are not needed, though I do prefer them. Very few league sites carry console games, and the games they do carry are very limited.
- skill level peaks in console games to a certain extent, in the PC FPS gaming world, the skill levels are on average higher and therefore more fun and a more challenging (you're not ending up playing against 10-year-olds over and over again; PC has a larger "Mature" crowd)
- Free 2 play games that rival buy 2 play games, surprisingly.
There are cons to PC that may drive players away from PC, for eg.
- PC has A LOT more hackers, depending on what game you play of course. Some games more than others, like F2P (free 2 play) games have significantly more hackers than buy 2 play games. (this is a HUGE problem with PC FPS, the hackers that is)
- PC has, for the most part, more "trolls"
I'm sure there is more, but I'm tired lol
overall, PC > Console, IMO
