byobu certainly looks good, and I'd recommend it to any new user. Having spent a while to learn all the shortcuts of tmux and customizing my env with tpm plugins, there's low value in me re-learning a new set of shortcuts. I also wonder how byobu users can use their system-defined Function keys while using byobu, since it seems to have set shortcuts on all these keys.
