I think if you have been Android for that long, unless you are tech savvy, you will have a learning curve if you go to iOS. For that reason alone, I probably would stick with Android.
That said, I am a big Apple fan, for both computers and phones. They just work. No virus issues. Their support is second to none.
A few years ago, I had to carry a Samsung Galaxy for work. I could use it for personal use, but never did. Despite flying over 120 segments/year, I preferred carrying an iPad for my personal use.
If you do go Apple, sign up for a couple of their classes at the Apple store (once the world starts turning again). It will shorten the learning curve.
