I’ve been running Chimera for about 8 months and love it. I’m very picky about package managers, and APK is up there with xbps (Void) in performance.
Almost everything I need I can run via flatpack. There are a few apps that I miss. They have a guide for porting them but I got lost last time I tried to get everything setup.
I thought about just running a container for those apps, but got lost in that setup too :). I’m waiting for some winter westher to hit so I have an excuse to stay inside and play with it.
GrapheneOS on a Pixel 9 Pro. It’s nice to have better control over what data is leaving my device. Updates / patches from upstream AOSP are usually offered in GOS in the same timeframe it takes to hit regular Pixels.
