I really liked the G2 as well. It was the first phone (at least that I saw) to put the power and volume buttons on the back of the phone, where a ton of later phones would eventually start putting the fingerprint sensor.

I replaced LG's ROM with CyanogenMod back in the day, and it was such a smooth experience. The main reason I moved on from it was because I cracked the screen and the replacement screen I got (installed by a local repair shop) had a touch sensitivity issue along the top edge.
