Zelda 2 was mainly hard because the combat was sidescrolling. In all the other Zelda's, you can move around in the 4 cardinal directions to avoid your enemy, then strike and work him down. Zelda 2, on the other hand, the enemies would come at you straight on and you had no escape except to run backwards, which you obviously couldnt advance if you did.
@Spitefull49, it was easier when you got the down stab (now notably also a key move in Link's smash Bros repetoir), but its still was far from easy, because some enemies had helmets on their head that prevented them to being attacked only like that.
In terms of 3d Zelda's, Majora's Mask is probably the hardest.
