better tags: e6 tags are more descriptive than booru tags. Furries are also adding natural language captions in latest versions to make it even better. Their max token length is around 600?, while NAI had 225, so they can use very long descriptions.
better setup: NAI itself is pretty bad, it's based on older SD1.4, and every anime model drags the shitty NAI with it, but furry models are based directly on SD1.5, and contain no NAI. Furries also use new training tricks like zero terminal snr (which did not exist when NAI was trained)
Also, for latest fluffyrock, dataset is over 3 million images, while all popular anime models are shitty NAI + dreambooth/finetune on few thousand images.
