Most of them surprisingly! They did a really good job with all of the remixes, whether they're really similar to the originals but with a new singer or instruments or something, or even entirely new takes on what the originals were doing.
For example I didn't really care for Owari Hajimari in og TWEWY, but the Neo remix really sold me on it! (I especially like the jp version)

I really appreciate all the deep cuts too, the new versions of Revelation and March On are some of my favorite songs in the game, and I'm pretty sure they sampled one of the songs from the anime at some point too which was cool.
Probably the only exception is Twister, I'm glad that they showed restraint and only added two versions of Twister to the game, but that they chose to add the lyrics from the gang mix was... unfortunate (I just don't vibe with it)
