The hottest model now is flux, and the community is gravitating toward it after the failure of stable diffusion 3.
Tooling around it is still nascent and it is very demanding (12GB+ VRAM GPU highly recommended) so you could also start with Stable Diffusion XL, fairly mature at this point.
I also use the DS4, I’m impressed by the work Sony have done there, especially by the out of the box support for gyro. No configuration for Dophin, Citras and Yuzu (and their forks). Literally easier than on Windows.
