They appeal to two different kinds of people. The first set (you and I) value the convenience of a job completed with a highly tuned and tested tool developed by word leaders in programming technology (Jetbrains). The other set of people wish to be able to tune things exactly as they wish, and focus on hyperoptimization of a set of known tasks that they become expert in.

Neither is wrong, but I do believe that when someone goes on about how if you just try hard enough to grok emacs, you will suddenly get it. Maybe. But I think there is an audience bias there, whereby only people who are inherently interested in tweaking and fiddling will achieve that benefit, and only people who wish to just get things done on a paid tool will be OK with using a mouse every so often. Horses for courses.
