Tech Reborn is the most notable I find besides Modern Industrialisation (if counting Fabric but otherwise Tech Reborn usually was a good go to besides the Unofficial and others on 1.12.2 for Forge) and a few others out there to continue GregTech in some form on newer versions. Forget if there is a others that do it on newer Forge but yeah I agree it offers a lot for a tech mod/expanding on what IC2 didn't do.
Tech Reborn is a wonderful mod too, I added it into the little Fabric modpack I made for myself and it was pretty fun, I stopped playing that modpack when my world became corrupted though.
Modern Industrialisation caught my eye when I saw it, although I dreaded the amount of re-texturing I would have to do (I am not really the biggest fan of recent GregTech's textures, no offense meant to the creators of the textures though, just personal preference) and thus I did not add it!
We use Pyrolusite's Minimalistic Technology for re-texturing GregTech Community Edition in our v1.12.2 family modpack, it was not a complete re-texture so I had to make some textures of my own to fill the gaps, it meshes really well with the new JAPPA style of textures!
