There are two major things for me: The first is the easy attachment to existing tmux sessions, ie. I just ssh to a server and it'll re-attach to my last tmux session automatically - F6 then detaches cleanly and logs out. The next is all the handy notifications in the bottom bar; a bit like conky, if you use that. So it lists the server mem/cpu/network load, number of packages that need updating, RAID status, AWS estimated cost (if relevant), no. logged in users, etc... It originally started out with a Screen backend, then switched over to Tmux which has a lot of the same multiplexing functionality. So that's probably why you're not seeing a huge added benefit. But the added extras are enough to make me always want Byobu installed - particularly the easy session attachment.
