I finished it a couple days ago. Overall, I think it was a good, but not great Zelda. Having finished it, I have that and Skyward Sword very close. I'd without question have Skyward Sword ahead of it, if not for the awful sword mechanics in it. I didn't have any issues at all with combat in WWHD, but SS it was an issue with me all the way through. But I liked the world more in SS. I had more fun in the dungeons. I thought the art design in WWHD was gorgeous though.
I probably give SS the slight nod, and would've given it a big nod if SS didn't have Wii-based combat, but I did like WWHD more as I went along. Still never got to truly like the open sea aspect of the game, but I came to tolerate it in the end and stopped hating it. Getting the ability to fast travel helped a lot toward the end. It was probably one of the easier Zeldas I ever played. Never died once in the entire game or came close to it. The bosses were insanely easy. I also thought the dungeons were a little long, and one time I had to quit midway through a dungeon, something came up. and it started me at the beginning, and I had to work my way back through. That was annoying, especially since you can spend well over an hour in those dungeons.
I'm glad I played it, enjoyed it, but far from my favorite Zelda. I really only have Majora's Mask to play of all the main Zelda titles. That's really the only one I've never played.
