I know that these "works for me" discussion are often not fruitful. But, I'll ask this: have you done a several hour session of typing/programming into a JetBrains IDE? I'm claiming that on my work Macbook Pro, even just typing plain text into a file and scrolling lines in IDEA is smoother and more responsive than doing the same in Emacs.
I use the Vim plugin for IDEA and evil mode in Emacs. Even things like holding 'j' or 'k' to scroll lines is painful in Emacs compared to IDEA.
I'll admit that if I spend some hours/days in Emacs, I stop noticing it much, so it isn't THAT egregious. But if I switch back and forth, it really sucks.
