Blegh, the whole argument is pretty much bullshit, to me. I find that there's a very vocal minority on both sides that loooove a flame war to flex their INCREDABAL SMARTZ, and in this day and age, there's more or less something for everybody anyway: some people are PC users, some are console users. It all depends on what you're used to; for example, I'm primarily a console person, because I grew up with a PlayStation controller, not to mention I'm not the tech-savviest girl in the world. I don't think one is 'better' than the other, because they both have pros and cons. While some games may play better on a PC than a console (and vice versa), if we're focusing on the big picture here -- the game as a whole -- then a slight difference in enemy AI isn't necessarily gamebreaking. Not to mention there's still a plethora of great games for every platform.
Personal opinion? If you're seriously arguing that PC IS ALWAYS BETTER THAN CONSOLE OMG, then congrats, you're a hopeless fanboy. PC vs. Console is no different to PS3 vs. 360, PC vs. Mac, etc. etc. Mix and match, my darlings. It's not always such a bad thing.
