First Zelda game I played was OoT. I played Wind Waker around the same time, can't say which I played first but my first experience with ALTTP was on the GBA.
A Link to the Past is a superior game, IMO. It's structured wonderfully, it properly rewards exploration, making the player find every wandering discovery feel as if it was intentional and worthwhile, and its level of difficulty is at a nice fair level. It's not Master Quest/Zelda II/Links Awakening nor is it Wind Waker/Twilight Princess/Skyward Sword whose difficulty levels have become a bit easy.
In my mind, it captures the heart of the series; along with the level of heroism intrinsic with the series, it captures th whimsy of exploration and discovery better than any game that came after it.
Obviously you're entitled to your opinion and all, but honestly I think there are few games that reward exploration as much as Wind Waker does. I barely ever complete games 100% but the console Zelda games post-ALTTP are one of the few exceptions to the rule.
In terms of difficulty there's no way Twilight Princess is easier than A Link to the Past, the dungeons in that game are some of the most complex and elaborate the series. I'd also mention the triforce chart thing in Wind Waker which is harder than anything in ALTTP but that's more annoying than it is hard.
If any game in the series is better than Ocarina, or ALTTP even, it ain't Twilight Princess. It's still good but, aside from the art direction and Midna, I can't think of any area where it compares favourably.
That's pretty important in a Zelda game though, it's one of the reasons why Hyrule is well-remembered as one of the most classic video game settings.
I feel like too many people disregard the importance of presentation in video games.
