My Nex has been wonderful. Currently I am running the Purity ROM with the Purity kernel. It has been amazing and have no desire to flash anything new. Through ROMs this phone has been improving every single month I've owned the phone.
But I am waiting for Verizon to come out with a decent replacement for my Nexus. Its been a great ride with Verizon but if they don't offer a decent phone by December I will take my 5 lines elsewhere. I require a fully unlockable phone without having to wait for exploits. A stock experience since I don't want skins.
If I had to choose something now I would go with the Nexus 4 probably with T-Mobile. I don't mind paying full price to keep my unlimited data since I only pay $10 per line for unlimited data with Verizon. But they need to allow another decent phone. Motorola and HTC no longer seem to be options.
