I haven't tried the new Air yet, but I've had pre-butterfly scissor keyboard MacBooks (e.g., a 2013 MacBook Pro and a few earlier-gen Air models), a 2016 (?) 1st-gen butterfly keyboard on a 15" MBP, a 2018 Air (2nd-gen butterfly?), and a 2019 16" MacBook Pro (1st post-butterfly scissor "magic keyboard").
I'd probably rate the pre-butterfly scissor keyboards as the best, but my 2016 Pro's "magic keyboard" is fine. My 2016 MBP 1st-gen butterfly is awful, IMO, not only because of the sticky key issues (I've got one or two that repeat), but it's also really loud/clacky. I don't love the reduced key travel, either. The keyboard on my wife's 2018 Air is at least quiet, but still less travel than I like.
FWIW, I believe these newer "magic keyboards" have less travel than the earlier-gen scissor keyboards.
