Mods that just makes the game look nice and runs alright?

Ok listen. I have modded skyrim heavily before but always every damn time, there’s a problem that makes me always quit that save. I haven’t even beaten skyrim in it’s entirety (do all the dlcs and the main quest I mean) due to the problems.

So dows anyone know a mod pack on nexus that can just be ok? sorry if this is a very common question.
