You can try any model you want, however I really suggest using Hassaku XL Checkpoint or AutismMix checkpoint
Note: When using Hassaku you might need to use an age slider though, I like the quality and the prompt adherence of the model, but it tends to age down the characters. (Or just use any other model of your preference)

Description
I tried really hard to check for any differences since they're pretty much identical twins and I couldn't find any. Nonetheless I trained a trigger word for each of the twins with their respective dataset, for the hardcore fans out there who might notice them apart.
