No .sog support? I can't tell if .spz or .sog is likely to win out as a de facto standard - or whether both will co-exist but annoyingly I've gravitated towards .sog as it seemed technically superior and I'd be mildly inconvenienced if it became a niche format.
.SOG is a partitioned format with LOD support, thus it is designed for massive gs3d scenes. SPZ is has neither of those features, and thus is simpler. Given that ThreeJS itself doesn't yet support partitioning and LOD for its gs3d data - although it will come eventually - I figured that SPZ was a good fit for its initial capabilities. SPZ also has wider support right now compared to SOG.
I don't know if the splat is exactly the same, but the playcanvas engine has no false transparency on this one: https://superspl.at/scene/7e4e9bcb that splat is actually of fairly high quality, so unless this is a materially different splat (with some of the gaussians dropped out maybe?) I'm inclined to blame the engine.
If you turn off performance mode this is way higher quality than either of the other two versions of this model linked by bhouston in this thread, although with a much lower frame rate on my phone of course:
