I'd have to say if you've got T-Mobile/AT&T, the 8+.
That's simply based on the fact that the 7/7+ are the first iterations with the Intel modem.
However the Qualcomm model (Verizon/Sprint) on the 7 (possibly 7+ too) has an issue with losing the signal so...
Just my opinion, I own a 7 Plus in jet black. I can't use it solidly as a smartphone. Dropped calls, no data, etc. So I'm using a V30 as my DD.
