Trackpads were universally abysmal, with the sole exception of the macbooks. They all had the frustrating diveboard design, every single one at every price point from every manufacturer. I’m sure you can buy laptops with decent trackpads online, but they had none in the store, macbooks excepted.
Keyboards were all over the place, but I notice that even some premium models are now carrying generic low end keyboard parts with weak travel, lack of key separation, num lock mashed into the backspace, and awkward arrow key layout. If anything I think keyboards are getting worse.
Screens are the one place where I’ll say things have improved noticeably, especially colors and black levels, although getting over 200 ppi and 500 nits is still a rare treat, and that is my bar for a compromiseless display.
