"You get what you pay for" best describes XBL, and if I could, I'd pay to get more on PSN.

Exactly.

I go by games. For me, the game offerings on XBL are better than those on PSN. Though, if you throw in WiiWare + VC (which you should), it goes:

WiiWare+VC > XBL > PSN

And with developers switching from XBL to WiiWare because of the better royalty rates and exposure Nintendo offers, it's likely that this will be a trend for this generation.

Don't let me confuse the issue by singling out games and pointing to the Wii. I think it's best we all continue to argue the merits of the other platforms' branded ICQ clones or incentive systems (i.e. achievements and trophies). Just avoid asking yourself why you need an incentive to play games on a system, or
whether "online community" is ironic as a description of what amounts to a virtual Detroit where you gun down strangers slogging you with textual abuse.
