This ROM works fine for me as daily driver. Nothing crashes here, it's fully stable and fast with the Boeffla kernel. All Lineage builds have Bluetooth issues and the camera app is poor. No stereo sound on videos, no 60 fps recordings. There is no ROM which runs more stable than stock. I've tested enough Lineage or other AOSP based builds.
I was in the exact same situation as you. I hated AOSP not cause it looked really good but the battery life and the sound bugs and performance issues
I used to get good performance on stock and everything worked well battery life was decent better than lineage os (then)
But I did get an issue where random apps will just shut off while I use them they didn't necessarily crash but they switched off and had to be restarted
I used to you use boeffla kernel
The kernel was great
After all these issues I decided to choose AOSP
It started horribly at first (pie) but as builds went on
Battery life got better and I found a sound fix and mic fix they work as they did in stock
I'm on android 10 now using the tuned kernel
Everything about this ROM is great camera is decent (not as good as stock) and performance is on another level
And now battery is more efficient because there isn't barley ant bloatware and I use v4a to tune my sound
I respect your opinion I would like to hear yours
