At least in my experience locon can give better skin textures

I tested dora - the advantage is that with different subtitles it is possible to train multiple concepts, styles, people. It doesn't mix everything up. But, it seems that it doesn't train as well as normal lora (I'm really not sure, maybe my parameters are bad)

I saw dreambooth from flux and the skin textures looked very good. But it seems that it requires a lot of vram, so I never tested it

I'm too lazy to train with flux because it's slower, kohya doesn't download the models automatically, they're much bigger

I've trained many loras with SDXL but I have little experience with flux. And it's confusing for me the ideal learning rate for flux, number of steps and optimizer. I tried prodigy but bad results for flux
