Effectively they are the same to me feature wise. The main difference is that Waterfox lets you login to your mozilla account and has the mobile app, so I can sync my bookmarks between devices.
Librewolf also lets you use Firefox Sync, you just have to enable it in the settings first. But yeah, I use Waterfox on mobile because Librewolf has no Android version
