I've owned my share of phones and the GS3 is the first phone that has cured my flashaholicism.. I am running cleanRom 4.5 and it just works. Battery life is all you can ask for and the phone has all the capabilities of any other phone. I have been 100% happy with this phone and have not had any desire to upgrade to anything else. With that being said, it is 8 months old and the S4 and HTC One are coming. At this stage, you may be best waiting for one of those two.
Verizon Galaxy S4 - MK2 rooted
Samsung Galaxy Tab 2 CyanogenMod 11 - Kit Kat
Nexus 10 - ThunderKat

RIP: GS3, Nexus, Thunderbolt, Incredible, Storm 2, Storm, Curve
