Sign Buyers Guide: Developer Edition Good or Bad?

I am in the market for a second HTC One 64gb. I'm likely purchasing off ebay.


Is there any pros or cons to buying the Developer Edition? I plan on rooting and installing CFW so the native android doesn't matter.
I've read somewhere you can get free 40gb of google storage but not if its tampered or dev edition.


Any other tips for buyers?
