I have used both for years and still continue to do so. Hate huge screen so standard iPhone and also a Huawei Mate 10 which so far has pissed every Korean Android phone I've had into the river. Having bigger thicker hands I despise rear fingerprint readers, on front is better for me. IF I ever had to go down to one phone it would be the iPhone no problem. Facetime, handover and iCloud see to that. If I ever had to have a single Android phone though it'd be hard not to go Chinese. Bang for the buck is incredible. Apps again are a different story, we have our own apps out there on both platforms and a considerable difference required in due diligence for both.
