What's the best image model for training non-photorealistic character LoRAs?

Example images are made using Flux1 with a two-character LoRA I trained last year. I found Flux1 to be pretty good at learning what a character looks like while not having its style be overwritten. In this case, I was using screenshots from a game (Assassin's Creed Shadows) and I was able to create images using the characters in a style that didn't end up looking at the game. I've also briefly tried Z Image Turbo and QWEN Image, but I feel those work best with photorealistic images. When I tried to train the same LoRA, then the style ended up being over.
