<- This has been my 'AI Suite' so far.
Out of all of them, TavernAI and gpt4all are probably my least favorite, but that's only because I'm picky and I like the options and control oobabooga gives me. It's also the same gradio UI/UX stylization as Stable Diffusion, so it suits my workflow better since I use both.
Although I will say, I have gotten much better performance out of GGML models using koboldcpp than any other of these FOSAI engines/apps/platforms.
