I would honestly call it a three way tie, with all three having Pros and Cons.
Wii:
+ Easily profited the most and more importantly proved Nintendo isn't dead yet.
- Alienated third parties further and fell way behind in the online space. Essentially they set themselves up to fail with their next one.
Xbox 360:
+ Captured major American market share and established the Xbox brand as something worth remembering.
- Overall there was only a slight profit made while still having ~6 Billion dollars in debt still left over from the previous Xbox.
-Sold worse in Japan than previously (Somehow!) and still failed to gain more world wide market share than competitors.
PS3:
+Proved a higher price point won't always fail and will go on to sell around the same amount as the Wii if not slightly ahead.
+Went from mediocre online support to arguably the best.
+Set themselves up for a great successor by keeping the games flowing and clawing back market share.
-Will essentially break even overall.
-Lost its major dominating position in the market.
