Help!! Recommendations please

I'm very happy with my Moto G7...

 

The GSMArena site has a handy phone finder function that might help you narrow down your choices. Go here and go through the various options:

Above all else though, and this has more relevance depending on where you reside, is full compatibility with your chosen carrier. (i.e. -- Here in the U.S. where carriers are very territorial and hostile to interacting with competing services, phone models are very defined. Be wary when buying branded phones. In the E.U. it's not as anal.)

Also keep in mind that your £200 budget limitation is contrary to a phone's long term prospects. Since you referred to updates as a factor as to why you're looking into upgrading to a newer phone, while Apple tends to support its own products much longer on a more consistent basis, with Android it's really a mixed bag. Samsung only recently stated it will support some of its product line for four years, Google has supported its Pixel line for three years, Motorola is a very iffy at maybe two years, and most off-brands may support their stuff for a year or not at all. The point being with Android, only flagship model lines 'may' be getting long-term support, but phones in that £200 price range it's not as likely.

So one option that doesn't appeal to everyone is to get something like a Moto phone, and replace it every couple of years when support for it ceases. Motorola makes some really good models at economical prices that are solid day-to-day usage phones, just adjust your expectations accordingly. Another thing to consider is if you're pretty well immersed in the Apple iPhone environment, you might find migrating to Android a bit aggravating. Transferring your iPhone user account data won't be a trivial process. So do this because you have specific reasons, long-term phone support not being a real highlight in the Android platform.

One last thing, and this is just a subjective opinion, is you'll find it easier to migrate back to Apple if you don't find it appealing to use Android. Apple makes its wall-garden difficult to get out of, Google is by no means benevolent about this but it does use more open standards and protocols on a much greater scale. Moving data out of Apple's oversight is going to be involved, moving data out of Android not as much.

But if you do move to Android, don't make direct comparisons between Android and Apple without the proper context. You'll be contrasting a new budget-class device with a dated flagship model -- this will involve countless pluses and minuses with both hardware and software aspects of both phones.
