LineageOS 11 (Android 4.4.4)

Stability: ★★★★★ (Best daily driver) Features: Lightweight, all hardware works (Wi-Fi, Bluetooth, audio, camera, sensors, GPS). Performance: Smooth for basic tasks (reading, YouTube (SD), music, e-books). Battery Life: Excellent.

LineageOS 12.1 (Android 5.1.1)

Stability: ★★★☆☆ (Usable but slower) Features: Modern UI (Material Design), more app compatibility. Wi-Fi, audio, Bluetooth work; camera can be buggy (preview issues). Performance: Noticeable lag on app switching. Requires reducing animations and using lightweight apps (e.g., NewPipe Legacy, VLC, Opera Mini). Battery Life: Moderate.

CyanogenMod 11 (Android 4.4.4) – Predecessor to LineageOS; same stability.

OmniROM 5.1.1 – Less known but very lean; good for AOSP purists.

What to avoid (for daily use):
