I can not run windows 11. I felt dirty giving it access to my Mac partition when I had a M1 Air.
The 2019 16" intel battery life is either great or crap depending on load. I pulled about 17 hours playing music in VLC with minimum brightness and low as 5 hours while doing actual work. The lowest wattage I've seen is around 4W on the intel while 1.2W on the M1 (screen off).
For consumers though, the M series chips are pretty darn good.
