They are all the same. If you plan on buying full retail just get the developer edition from HTC. It's bootloader is already unlock and rooting it won't void your warranty. You'll get LTE with almost every GSM carrier (T-Mobile, AT&T etc) but you can't use the phone on CDMA carriers
Converting the developer edition to a GPE would make it the same device.
