I wish the comparison could also include "message sync across devices". Currently Signal requires one to export past messages in a file (that can be unencrypted). This means that to be sure to keep their messages if they use new devices or lose their old one, one has to use a cloud storage, an area where privacy violating providers are still prevalent. Note that WhatsApp was doing exactly that (with an opt in IIRC) with google drive sync on android and I guess iCloud on iOS, so I always found even their e2ee claim dubious. At least Signal doesn't make it easy to use unencrypted cloud storage but I wish to see more services with message persistance. On the other hand, it certainly has a much higher server cost.
