Your editor is not the bottleneck, but reducing the distance between your thoughts and the code is still pretty important. You want to be able to move around, type something and change your mind in the most immediate way possible. Whenever I have to revert to an unfamiliar or inferior editor and can use no motions except from the mouse or arrow keys, I feel like everything becomes harder because I'm not "in" the code.
In the same way, having a compile time of 10 seconds instead of < 1 second is probably the main bottleneck when you code, but your productivity will suffer.
