Don't even consider v.1... v2 is a way better.

All examples were generated in just 8 or 10 steps

cfg: 2.3
sampler: Euler A cfg++

alternative sampler: lcm (you can increase quality with this one by using more steps) 10 steps with lcm sampler will give you good details quality

lcm + ddim_uniform + 10 steps have very good results - try it as well.
