To me, among the open models, there's just nothing like Minimax H3 (and its variants). Natively, it's not optimized for naughty stuff, but there are ways around that, and some alternative merges that allow for some nice stuff. Granted, I don't toy too much with realistic imagery, though it can be competent for that too. If you have lots of VRAM, it can generate some stunning videos in HD, 2K and above.
