Ran a search but most "comparison threads" between the Galaxy Nexus and Galaxy S3 were pre-Jelly Bean. I'm torn!! I have Verizon and an HTC Thunderbolt right now, rooted with CM7. The Thunderbolt has speakerphone/voice quality issues, battery life is atrocious with moderate use, the screen is terrible in daylight, ICS 4.0 still has not been officially released, ICS-based ROMs are buggy, and my Wi-Fi decided to completely stop working (a somewhat common problem on Android 2.3 apparently with no real universal fix). Safe to say, I am FED up with my Thunderbolt. To add to my dilemma, I want to keep my Unlimited Data plan which forces me to pay full price for a phone. I don't mind the used marketplace (via Ebay/Swappa) as long as I find a near-mint unit. I can get the Samsung Galaxy Nexus for about $250, or the Samsung Galaxy S3 for about $400. I know Verizon will sometimes have a sale on their CPO inventory, but I have not seen one in the last few weeks. Here are my daily uses: I prefer Stock AOSP over Sense, TouchWiz, or any other OEM interface. However, I know you can root and throw a Jelly Bean ROM on the S3. Voice and speakerphone quality are an absolute must -- especially the Speakerphone for when I'm driving. I text and surf the web a lot, so the S3's bigger screen is nice and using LTE is a great perk. I don't ever watch Netflix or movies. The photographer in me doesn't find AMOLED screens to be nice from a color rendition perspective. I take occasional pictures "for fun" but I'm a semi-pro photographer with dSLR equipment. I will occassionally use Flash (e.g. if a website requires it) I don't play any mobile games (since I have a gaming PC, Xbox, PS3, etc. to satisfy those needs) Most tech reviews say that the S3 is, hands down, the better phone. However, I don't know if my actual uses justify the extra $200-$250 for the S3. Or maybe I should be looking at another phone? Final scattering thoughts: Speakerphone issues with the Galaxy Nexus was cleared up with a recent update. CM10 is still in Beta phase with the S3, whereas Jelly Bean is officially out for the Galaxy Nexus. I'm semi-tired of fiddling around with ROMs, Kernals and Radios. Just want something that works!! Battery life on the S3 is awesome, while above-average on the Galaxy Nexus. I hear Google Now is a battery drain. That might sway me away from the Galaxy Nexus. I am anxious to have a smooth user experience via Project Butter under Jelly Bean. I miss having a physical keyboard, but the Samsung Stratosphere and Motorola Droid 4 both stink.
