To me, they complement each other. Sometimes I want to use the (mostly) pain-free consoles and just play a thing even if I'm paying a small premium for it, sometimes I like the open (or at least configurable) nature of a PC game and the accomplishment of squeezing that last drop of performance out of it.
At the end of the day, though, it's about those hot 'sclusies. I like to have my bases covered and be able to play whatever catches my eye. Within reason, of course... I'd like to own every platform, but considering that my wallet made a cartoon "wheeze" sound effect while dust and moths flew out the last time I opened it, that ain't a-happening.
