Question [Q] Question about a replacement.

I am a verizon user and currently on an HTC Thunderbolt with santod's rom. The issue is it is slow and now will not charge well where it plugs into the phone. I have been thinking of getting a new phone but not sure which way to go. I know I will attempt to root it and still want a large screen but better battery life. Can someone kindly tell me what the best phone out there might be and why? I need to do something quickly.


New Phone:
Verizon HTC One M8 | NuSense 6 | TWRP Recovery

Old Phones:
Verizon Thunderbolt | Rom: NuSense

XV6800 | Rom: DCD 4.1.2 | Radio: 3.42.40 | SPL: nueSPL-2.47
