I just gave Protogen a spin and the diversity of outputs it gave me was abysmal. Every seed for the same (relatively open-ended) prompt used the same color scheme, had the same framing, and the same composition. Whereas with SD 1.5/2.1, the subject would be placed differently in-frame, color schemes were far more varied, and results were far more interesting compositionally. (This is with identical settings between the two models and a random seed) So unless you want cliche-as-fuck fantasy and samey waifu material, classic SD seems to do a much better job.

Yes, protogen is based on merging of checkpoints. The checkpoints it's merged from are also mostly based on merging. Tracing the degree of ancestry back to fine tuned models is hard, but there's a ton of booru-tagged anime and porn in there. If there's one style I dislike more than the bland Midjourney style, it's the super-smooth "realistic" child faces on adult bodies that protogen (and its own many descendants) spit out.
