In 2018 I switched from Vim (used for 5 years) to Emacs and I have no complaints about RSI/CT. It may be because I also learned to properly type with Dvorak at the same time. Unlike most Vim switchers I don't use Evil because modal editing just doesn't work for me. I always find myself having to change mode to do something and half the time the mode change doesn't take and shenanigans occur.
