Anything with split iGPU/dGPU was a mess no matter what and where, WiFi that was not Intel was a mess, suspend to ram and suspend to disk were a coin flip if the system would wake up again or if it would decide to wake up on its own and overheat itself to panic.

"I installed Ubuntu on peoples laptops and was extremely lucky they happened to have compatible hardware or didn't notice the stuff that didn't work and had a non-borked firmware". FTFY.

This was absolutely not everyones experience, including mine.
