That’s not really a comparison you can make, not just from a speedrunning perspective but from a game perspective too. Not only are the 3D Zelda games completely different (OOT plays drastically different than TP or SS), the glitches and tricks required for them vary greatly including setups. Each game is hard and easy in their own regard.
sorry didnt really explain well, i just mean like just in difficulty of playing, not speedrunning, just casually what are your opinions on them
Well pretty much the same thing. No game is really that hard to play casually, especially Zelda. The series is generally pretty forgiving to new players and the games tend to have a decent learning curve (NES ones excluded). So, none of them are really that difficult to play or get into. Skyward Sword can be a bit harder if you’ve never done motion controls for a game or Majoras Mask might be hard with the time restrictions, but even those aren’t terrible.
As long as you’re generally good at puzzles and exploration, you won’t find any of the later Zelda games very hard to get into. I personally can’t rank them beyond that because none of them (aside from maybe SS) have any parts that are incredibly hard to do.
