I owned all three consoles... My 360 red ringed before the warranty extension and my Wii had to go in once (I still have problems with the Wifi). I sold my PS3 because there were no games at the time and I was making a profit.
Before this gen I never had to call tech support, now I've called all three.
Hardware:
F for MS (Just a complete mess, no standard HDD, no batteries in controller, no Wifi) ,
C for Nintendo (Meh wifi, shoddy build campar, not enough storage, batteries, but it works),
A for Sony (built in batteries were nice).
Software:
A for MS (So many games)
B for Nintendo (Great 1st party line-up)
B for Sony (Good 1st party line-up, decent 3rd)
Online:
C for MS (Money, for what exactly?)
D for Nintendo (Would be an F if it weren't for VC and WiiWare)
C for Sony (Not as good as MS, but much more bang for the buck)
Overall Grades:
D for MS (Great games, too bad nothing to play them on... I know they fixed some HW problems and about Customer Service improvements, but they weren't there for me when I bought mine. The great library may convince me to give them another shot)
B for Nintendo (Super Mario Galaxy, Bunch of decent budget titles, bunch of innovative games VC, WiiWare are awesome - Lot of gameplay for the money. Crappy online experience overall though along with weak mature variety)
B for Sony (I'm still waiting for a reason to re-buy. Great HW, great value with BRD, Wifi, rechargeable controller, HDD, free online. Just nothing compelling me to re-buy yet.)
The Winner:
Nintendo DS.
I would cite regulation, but I know you will simply ignore it.
