I'm overdue for an upgrade... been limping along with my D1 on Chevy's latest steeldroid... it has breathed a little life back into it for the time being.
I love the idea of the Nexus... the ability to easily root and mod and even get the next version or 2 of Android guaranteed, or more. I've read battery life is decent too. Price is still high though ($250 through bestbuy since I signed up for the $50 credit during February). I know Samsung usually makes good hardware as well.
I love the idea of the massive battery of the Maxx... as I live in an area with poor reception, but work most of the day in the City nearby that has great reception. My concern of course is the battery... I had to replace the battery in my D1 before my 2 years was up because it wasn't holding enough charge. It would drop from like 40% to 10 in a matter of an hour or two (depending on usage). I don't like the inability to hack it as much... as I have really enjoyed tinkering with my D1. I don't HAVE to mod, but would prefer to be able to, especially since Moto is crazy slow on upgrades. On the flipside their hardware is top of the line, which is also very important to me. Price is high.
I have read some good things about the Rezound. Good price ($199), great sound, decent battery but sometimes problematic. Top of the line screen quality/resolution. HTC can be unresponsive on upgrades as well, from what I have read, however it is unlocked, is it not? I read one article that described the Rezound as essentially a great middle ground phone the unfortunately has been largely overlooked.
So, my order of needs would be:
#1: Call quality, clarity, and ability to maintain calls. That's what a phone is for afterall, is it not??
#2: Reliability. Hardware and battery.
#3: Mild to moderate usage for 8-10 hours minimum, on LTE
#4: Ability to customize/hack/mod
#5: Price (mainly will determine how long till I can afford to upgrade ).
I usually won't root my phone for the first year to maintain the hardware warranty, and avoid the expensive monthly warranties. However I have read its usually possible to fully unroot, so I may end up rooting sooner this go around. The main reason I rooted my D1 was the lack of upgrades.
Looking forward to your input! I'm so ready for a new phone... just really torn on which one! FYI, leaning more towards Nexus or Rezound at the moment...Nexus more than Rezound by a small margin, mainly due to the hackability. The locked bootloader bothers me more than anything about the maxx...
