Use CFG 1.0 (or slightly higher if you don't care about speed)
Sampler: Euler_a
Scheduler: optional (I'm using beta)
6-12 steps
This model have a good balance between quality, creativity and speed. You can generate good looking results in just 6 steps (10 steps will sometimes reduce amount of possible errors like number of fingers).
I don't recommend 16+ steps - it's sharper but less "creative". Use 8 steps and upscaler for better experience.
