It is tough to call, guess it is based on your agenda, which locks you into a certain argument.
Nintendo - Wii because it sold more lifetime, period. 360 lost as it sold the least.
Sony - PS3 has the most momentum now and outsold the 360.
MS - Xbox brand gained market share gen over gen while Sony lost it. Xbox division profited much more then PS division, which still is in the net red from 2005-2008 losses. PS3 clearly lost.
We can't change our arguments and can't be convinced otherwise lol
