Pinnacle of discussion was the Frame Interpolation
Primitive SFM animations can definitely surpass some Blender cum animations.

is one of my all-time favorites; This doesn't mean Blender is inferior/SFM is superior; I consider Redmoa to be one of the best cumshot animators out there.

is actually really good. The key to a good cumshot (from my unprofessional opinion) is having ropes with cloth sims. the natural proteins in cum make it "stringy" or "streaky", so ropes + fluid with relatively high surface tension and a little bit of particles for flair make for a really good cumshot where you get that natural stick and right amount of fluidity, and the particles add for the stray sprays of cum that don't really appear but shoot out. I've yet to see all of those applied together so I'm not completely sure on the stuff I'm seeing, but I'm drawing from memory and from what I know about animation.
