OP7Pro is a good device only the OP can determine if it's the right move. I use my Samsung Devices to it's full potential which is why there is no other that can dethrone it as my primary device. I use Samsung Pay, Gear VR, Secure Folder,DeX, wireless charging, pictures and video around water. Also, with Samsung's apps like GoodLock, OneHandOperation+ and Samsung themes, it can truly be a customizable experience that others can't provide. I wouldn't be able to do lots of these things with the OP 7Pro.
So the question to the OP is what do YOU use a device for or what do YOU want out of a device?
