This was 168 images that have been posed in reality capture. Every training took a bit more than one hour on my RTX 3060.
Postshot (in the front) created by far the most splats. But the shape of the splats is rather bad. This still features the most detail, but I would say it has the best quality.
Brush (in the middle) got soft surfaces and reflections work best in all three models. However, small details have been radically simplified.
Nerfstudio (in the back) provides the best balance between quality and number of splats. Unfortunately softer surfaces with reflections don't work as well as for example in brush.

Yea,I would like some more scientific results with more variables too! Would you please... ;)

This is a really nice comparison. It could be interesting to compare across a similar number of splats and also compare with Nerfstudio splatfacto-big with bilateral grid, since I found that to give great results.

Postshot is the king for me

Actually file-sizes are these:
brush: 192MB
nerfstudio: 575MB
postshot: 726MB
however, this is before cleaning up.

Actually, on reflection, the Postshot version beats the Nerfstudio version in a few areas too so it's not totally clean cut. But unless all three have a similar number of gaussians, it might not be a fair comparison.

Why didn't you constraint the Postshot version to a smaller number of splats (via MCMC)? Personally, I like the Nerfstudio version best. The test (AirBorne Pro Instrument etc) is unreadable on the Brush version - but it quite nice and crisp on the Nerfstudio version. Since the Nerfstudio version is at least as good (if not better) than the Postshot version, but with presumably much fewer gaussians, that's the winner! Thanks so much for post this comparison! BTW, what was the gaussian count for each exactly?
