YACAM is just an abbreviation for "Yet Another Cartoon/Anime Merge" and SR is "Semi Realistic"
In different versions they can pretend to be a photo-like model, but the main purpose is artistic style. As for me — "true photo realistic" models are boring. I'm ready to trade a bit of "natural skin texture" for "glowing eyes" etc.
There have already been so many merges here and the key idea of this one is using "broken", "over trained", "strange" models as a part. Unlike other (really good) typical models my one(s) might be less stable, but likely might compose a bit more intrigue results.
Higher numbers in "version" mean just the models order, not how they are "better/worse". Please, read their own descriptions.
