Well, it depends on your system. In my experience, Emacs without native-comp is way snappier on Linux than on Mac and Windows -- and getting native-comp working is also much easier on Linux, which has a big impact. Large numbers of pixels (high-DPI / Retina displays) can increase stuttering and flickering in the GUI version, in which case performance can improve by using `emacs -nw` in a GPU-accelerated terminal (Kitty/Alacritty), or maybe by switching to a different GUI frontend (e.g. the NS Port vs. Mac Port on MacOS, or the X11 vs. PGTK version on Linux).
