This mod certainly does add a lot of new blocks, and I would agree it is a lot better than similar mods like Rechiseled texture-wise. The crafting benches for getting new blocks are very nicely textured and modelled and fit very well thematically. Additionally, the extra foliage designs can be really nice for adding variations, and the case where a new texture has been made for a single block palette is normally done really well.

However, all mods like this suffer from the issue of quantity > quality and many of the textures have odd contrast or just feel too alike. Furthermore, sometimes when building these extra blocks make it harder to create cohesive block palletes due to choice paralysis and having so many similar options, which can actually make building more frustrating. Lastly, the variations on things like foliage and dripstone often aren't understood by other mods correctly due to tagging, so it can sometimes lead to unintended frustration.

I would recommend this mod only if there are some specific block textures in it you are looking for, otherwise I'd focus on getting more mods that add unique variation to different blocks rather than providing same-y recolours of a few patterns.
