I've always personally viewed it as villian>realface>unbalanced>dlight>dflsae>dflh128>dfaker>original>IAE>lightweight
That being said, I never use villian or realface, dlight, because even though I think they are "more realistic"
what ever realistic bonus is not worth on average taking on average 3-6x times longer to train.
Unless you are the person who has a powerful computer and you are willing to just let it train for several weeks,
I'd have to guess you might get a better product if you had a medium or low quality model
and let it train to its true completion rather than a high quality model that's not trained enough.
Personally I'm finding dflh-128 to give almost perfect realistic results on 720p and 1080p videos and good results
for 2k and 3k VR videos with 60 hours of training on a Geforce RTX 2060, using high quality data
Oh and for context, I'm calling viallian, realface, unbalanced, as high quality models from high to low, dlight, dflsae, dflh128 as medium quality from high to low, and dfaker, original, IAE, Lightweight as low quality from high to low
