My new i9 15" is a lot cooler and more silent than the i7 2015 it's been replacing. I guess doing a completely clean install with nothing else than using iCloud to sync data from the old machine fixed a lot of software related performance issues that piled up on the old one. I expect the 2015 to be a lot better again after a clean install. I think most of the problems on the 2019 are software related.
Not seeing any of the heat / performance problems mentioned by other people, the only really weird thing I've seen is that the color palette was way too dark getting out of sleep until I minimized and maximized brightness. That helped until the next sleep where it was too bright this time and the brightness trick didn't work anymore. Finally fixed it by switching between another color profile and back.
Otherwise TouchID was pretty good, don't really notice the touchpad in any way good or bad and the touch bar goes largely ignored just like the row of keys it replaced. Keyboard action is nice, it's slightly more clicky than the 2015 but still has about the same travel.
I really doubt anybody still on a 2015 or older will regret getting the 16". Probably the software problems get ironed out over the course of the next months.
