I'm really fond of these games but both have annoying sections with heavy backtracking (Ages especially).
To get an idea - Ages contains - The Tokay Island trade section , the Goron minigame section, and to a lesser extent you could even point to overuse of that 4-way clockwise only turnstile thing that forced you to find a way to make figures 8s in multiple dungeons.
Seasons is bulked out a bit compared to Ages (with subrosia, and you know, 4 variations of every overworld screen) I think the Gameboy era item switching rears its head in this game more than in Ages (Or even Awakening) because it makes use of combo items like Bomb+Arrows and Seeds(mostly peagusus)+feather. Having shoulder button quick select or better would be much appreciated in Seasons.
I think both games are a pretty interesting take on Zelda though - The time spent on overworld to get too each dungeon is a substantial mini-adventure in itself (sometimes too much) and the dungeons themselves are kind of clever, with their main fault being excessive. Much more heavy use of puzzles (including item-less puzzles with things like the tile puzzles) than seen in Nintendo's own 2D zeldas (I prefer them to a lot of Link to the Past / Minish Cap dungeons tbh). A few of them need serious reworks (Jabu Jabu's Belly's attempt at 3D with the water levels doesn't work very well). And the 4-way turnstile is overused (backtracking within dungeons after the backtracking forced by the overworld is kind of a slap in the face).
Other things - Both games have "introduction" sections for the 3 mounts (Moosh the bear, Ricky the Kangaroo, Dimitri the Dodongo) as well as 1 overworld/psuedo mini dungeon area that is completely transformed depending on which of the 3 you choose to be permeant later on . Compared to 3D Zeldas though you don't really have a "mount" feeling with them, because the amount of items needed to cross any 3~ screens on the overworld makes also switching to hem on top of all the other items you need feel bad (nevermind peagusus seeds outclassing all 3 of them). I don't want them to "flatten" the overworld, but it's just an observation that maybe the flat overworlds in OOT/Twilight/Windwaker/etc had some good points in this regard
