I have no idea why the defaults are so bad, but I've kind of got used to that as a Linux user ¯\_(ツ)_/¯
Did you ever try the 3-finger drag on a Mac? I find it hard to imagine any button being easier than that.
It’s a shame Apple hides it in Accessibility. That gesture is wonderful.
It's all about the software. Scrolling in Firefox on Wayland with the upcoming vsync patch (https://bugzilla.mozilla.org/show_bug.cgi?id=1542808) and OpenGL layer compositing enabled feels perfect. (Fun fact, I actually contributed the inertial scrolling on GTK patch to Firefox :D)
If you run legacy software and your trackpad scrolling is delivered to the application as emulated scroll wheel events, don't be surprised that it doesn't feel right.
If you write or code or otherwise do real work, then something like a thinkpad has input better optimised around that.
But if I had to pick a keyboard I never actually have to type on myself - I would pick the Apple keyboard 100% of the time.
Btw not sure why you compare trackpad to a mouse. People who commute or work from cafes need good trackpad and apple ones are the best. The trackpad itself costs much less but i doubt people would use it as mouse replacement in office situations.
I also did not change any setting on the trackpad. This is out of the box.
