I adore LineageOS and official support has now become my #1 factor in choosing a new phone. I've been running it on my Oneplus 5T which was already two generations behind when I bought it and there hasn't been a single day in over a year of ownership when I thought it wasn't fast or responsive enough. It's incredibly stable, there's no bloatware, and I get updates every night, which means I'm always on the latest security version.

If this thing ever breaks or dies I'll probably get a Zenfone 6 (I recall Asus actually openly distributed kernel sources with the express purpose of helping out the open source ROM community) and I'm excited to see how LineageOS runs on that.
