I did the same thing a few years ago when I finally dropped Sprint for Verizon. Seven phones in total over two accounts, and things have never been better. Previously it was a mix of feature phones, iPhones and Androids, all with various versions of things and features, and a headache for me as the de facto helpdesk. Now, everyone is happy, all the devices are the same, and tech support is so much easier. I'm even considering running OS X Server for some light MDM to really automate the remainder of my problems away. Most, if not all, of our extended family are also on iPhones, so FaceTime is a breeze, and iCloud Photo Albums are the assumed way of sharing things - when they made it such that anyone could add to an album, it was a game changer.
