WW has many drawbacks that seriously compromise it. Empty overworld, terrains feels the same all around, very few places to visit, long time to travel between islands, boring to death quests, non-existent difficulty (I finished without dying a single time and I'm far from being a top player). The reason why it's so acclaimed the way it is is because of the art style and direction. If you remove the art style it'll be an average at best Zelda game. It was the first Zelda game for many of the GCN/Wii generation so they are very personally attached to it.
I don't get why WW fans complain so much about TP being slow and overworld empty while WW has the same flaws. Because WW was the kick off for the GCN/WII generation, they also hold a rivalry against the N64 titles, most especially OOT, for the most influent 3D Zelda ever. A major reason why TP get some backslash from WW fans is because of it's strong connection to OOT art and gameplay wise, so they rather prefer to praise something running away from the OOT/N64 formula and more attached to GCN/WII and their generation.
