I probably just don't buy games that would benefit from a controller. Plus, I was coming at it from the angle of online play in an FPS (which are most of the Steam games I play).
As a side note, I bought Bioshock Infinite when it was on sale for $10. Really, really fun game. I think the only major gameplay gripe I have is even with vigor upgrades, there are a couple of vigors that are easily the best, a few that have situational uses and then a few that either cost too much salt to be viable in a given fight or really just aren't very useful. It would have been nicer for vigors to have more equal effectiveness, and then be up to the gamer to choose the one that fits their style best.
I also wish weapon upgrades were more visual and that some of the weapons had more upgrade options.
