What's the least conflicting prefix/escape sequence for screen or tmux?
Problem
Screen goes with Ctrl+A. tmux on the other hand—as developed within screen—uses Ctrl+B. Both keystrokes, however, are also used in editors, shells, etc. Thus choosing either one degrades the user experience and functionality of those tools when used within tmux or screen. What prefix conflicts the least with other programs' and shells' keybindings?

I think (a.k.a. ) is the best if it's in a convenient position on your keyboard layout. Its uses in other programs are quite rare: sending to a process aborting for or while loops in a shell when is intercepted in emacs I don't know of any other uses. Be careful to not accidentally kill a processes outside of or after getting used to it. It happened to me only once in a few years though.
