I can answer tangentially as a screen user for a couple decades that if you put something like
if [ -n "$SSH_TTY" }; then
exec /usr/bin/screen -xRR
fi
in your .bash_profile then where ever in the world you log in via ssh, you'll instantly have exactly the same environment, as if you never disconnected. Simply "Ctrl-a z" to disconnect and later reconnect "somewhere else" exactly as if you hadn't disconnected.
You can do something kind of like that with a tiling window manager if you put VNC in between the user and the window manager, such that all access is via VNC. However VNC doesn't transparently remap like screen does, so you can get icky issues with mismatched screen resolutions in VNC. In that way screen/tmux is MUCH better than doing something kinda like it with VNC. OR rdesktop, or whatever.
In .screenrc I'd suggest startup_message off, vbell off (because I don't like it), and some lines similar to bindkey -k k1 select 1, bindkey -k k2 select 2, so that function keys insta-switch you. Also I have a "caption always" line that resembles line noise but it begins with the hostname and shows exactly which sessions I've opened and highlights the one I'm looking at right now. I probably last messed with it 15 years ago so I don't remember how it works.
You can put lines in .screenrc like "screen -t bash 0" to autorun a bash shell in screen 0. You could put something like "watch procinfo" in screen 0, or tail something, or whatever.
For all intents and purposes screen overlaps tmux about 99.99%. There is a small 0.01% area where featuresets and bugs do not overlap. There's a cultural thing where "most" screen users know about screen and tmux, and "most" tmux users don't know about screen, which is mildly interesting.
