The acceleration curve and default scroll speed are pretty horrendous in linux in my experience. The advantage of course is I can just add a command to my init file to adjust it but the scrolling speed isn't exposed in the settings apps of any of the major DEs as far as I know.
Yeah. NixOS has facilities for adjusting those acceleration curves and scroll speed in a universal/pre-DE way, as well.
My preference is to disable acceleration in favor of very high sensitivity for physical mice, to disable small touchpads (like on old Windows laptops) and retain a substantial but smooth acceleration curve for large touchpads (like on a Mac).
I think the DEs often let you adjust how many lines a single scroll increment scrolls by, but not the size of movement that triggers a scroll increment on the touchpad. I think depending on your touchpad driver (evdev is usually more flexible than, say, synaptics) and maybe your choice of display server (Wayland vs. Xorg), you can adjust the other aspect of touchpad scrolling.
