may i add, (yes i read it all, damn, give me an hour of my life back plz), the best thing to do is to try them out, both, with the same game, at the same time. go to a toys'r'us or something, try it, feel in analyze it, ect.
i liked 360 much more than ps3, may i quote myself
360 is superior in graphics, ergonomics, community and online service. also, cheaper
all this based on my experience on both consoles, i usually dont pay attention to numbers (except prize, of course)
