My upgrading dilemma.....

I'm stuck between a metaphorical rock and a hard place. I have a grandfathered account with Verizon that has Unlimited EVERYTHING. That's right, everything. Minuets, messaging and data. The holy grail of plans. I'm using a Galaxy Nexus running stock JB 4.1, but I'm getting tired of all the crap surrounding the phone and its update procedure. So my big question is, should I drop and go with the beautiful Nexus 4? (Which is sitting in my closet unopened) Or stay with Verizon and hope for something worth while to purchase off contract?
