As for the animations...
The second animation is a bit more... High fidelity in some areas? I don't know what to even call it. The clash of different pixel art styles is what I find jarring[^1].
But I guess my point was that neither animation is even _good_... Like both of them barely pass a cursory glance; there's lot of nonsense going on in both of them, that wouldn't get past any animator. So, I wouldn't say one is better or worse; they just different
[^1]: Edit for context, I used and even made _a lot_ of pixel art in primary school and my teens lol
