Zelda II
A Link To The Past
The Minish Cap

Legend of Zelda is the most perfect.

But Link to the Past is the best.

I haven't played them all (Missing 1,2,DS games, 4 Swords GC), but I'll go with A Link to the Past, it's one of the few rare games that I can pop in at any time in my life and replay it without getting bored.

There can only be one answer. A Link to the Past. Simples. I still play it to this day. One of the finest games on the SNES.

I would have to go with choosing Four Sword Adventures. It's very good game, in multi- and singelpalyer. I have had very good memories with that game.
My order would be this:
Adventures > AoL > LttP > LoZ > MC > LA > The Inferior Four Swords

Link to the Past was really good, but I also really liked Minish Cap

My first Zelda game was LoZ, but the one I played most first was Adventure of Link.

I love A Link to the Past, but actually I prefer Link's Awakening. Not for gameplay reasons per se, but the humor and the ability to play an excellent Zelda game on a handheld made LA the right Zelda game at the right time for me.
