I run Lineage on a Pixel 3a xl (no google), and a OnePlus 5 (mind the gapps).

I have found both to be completely stable.

My first Cyanogen phone was an HTC Incredible, and I don't remember any stability problems.

Same. LineageOS is what allowed me to use devices I liked for as long as the hardware lasted, instead of being forced to buy the new crap.
