Me personally - I'm feeling the Jet Black 7 Plus (for the 2 cameras), coming from a Rose Gold iPhone 6s. On T-Mobile Jump on Demand, it's a free upgrade (2 year contract renewal) - I always get the lowest size as I stream most music I listen to and pay for a larger (50gb) iCloud drive. Always for personal and business use - never hurts to test on the latest and greatest.
