This is a great phone and development has really picked up since KitKat's release. There is now a stable build of CM10.2 (Jellybean) available and there are multiple KitKat ROM's. Developers have even been able to port the stock LG camera app to the AOSP ROM's like CyanogenMod, AOKP, Paranoid Android, etc., so that you don't have to use the crappy stock Android camera app. I've never really understood why this phone isn't more popular. LG's UI, while similar to Touchwiz, performs MUCH better with no lag. It's also a lot more customizable. There are tons of ROM's, mods, etc. that can be loaded on the device, and battery life is top-notch, even beating out the Note 3.
The G2, Moto X, and Nexus 5, are the best phones that you can get right now. You can't go wrong with either of these, and they're all much better than the Galaxy S4 and HTC One.
Looks like I'm coming back to my trusty G2. Returned mine after experiencing horrible GPS issues (rendered navigation useless) and ended up giving the Moto X and Note 3 a shot in the meantime. Honestly would've kept the Moto X if I wasn't able to get such an amazing deal on the white Verizon G2, but that's another story. I'm glad to be back and am excited to see that CM10.2 is now released as stable along with developers successfully porting over the LG camera app to AOSP/CM ROM's. My white G2 will be here Thursday and the first thing I'll be doing is rooting it, modding it, and putting a ROM on it.
How's yours holding up? I'm really hoping this new G2 doesn't have GPS issues like the last one, as that was pretty much my only real problem with the phone.
