Out of those, it seems Jitsi and Mediasoup to be better as SFUs than the rest because they have what appears to be decent-looking congestion control, bitrate allocation, and support for simulcast. The rest apparently do not (at least I couldn't find anywhere in the code where it happened).
Also interesting to note is that so many of the newer ones are written in Go based on Pion. If Pion ever gains the ability to do decent congestion control (perhaps based on transport-cc like Jitsi and Mediasoup do), that could improve things for all of those.
I really think it has gotten way easier in the past couple years. I am biased though, don't want to think my effort has all gone to waste :p
