The thing about your opinion is kind of wrong because games literally look better now, and it's fact on what the best console looking console not opinion. You can't bring opinion into facts and technicalities, you could say that you liked it the best because of it's Pixar/Disney look.
"Best-looking" is a judgment formed by one's opinion. More polygons, etc. is something that can be argued based on facts. But when taking art style into account, then what looks best to someone has everything to do with one's visual preference(s).
For example, I believe Mortal Kombat 3 looks better than Mortal Kombat 4, regardless of the fact that MK4 was built on a more powerful engine, and required better CPU and GPU processing. MK4 was more techinically evolved and still looked worse. This has been my opinion of which game is better-looking.
But back to the point of this thread, I stand firm by my opinion that Windwaker is not one of the best-looking games of all-time.
