All you are really saying is "I am used to screen's behavior and keybindings". That is fine, but it doesn't delete the huge amount of useful functionality in tmux that is not in screen. Nor does it make screen "simple" or "mature". Screen is old, not mature. It is fragile and brittle and clunky and inconsistent. Which is not surprising given its age and lack of active maintainers.
