This isn't 2010 where smartphones are the new fad. Unless you are a senior citizen with Alzheimer's, jumping from iOS to Android will cause the least friction, since the OS basically behaves like a pocket PC. Can't say the same for users jumping from Android to iOS.OP, if you have been using iPhones for a while then you indeed will have an experience with Android See how long you can last before reverting.
Anyhow, if you must, then Pixel software will be the closest to iOS in terms of coherence. Other than the fact it will also offer the best still camera. Poor after sales, just okay battery though. If you seek features whether useful or otherwise, Samsung it is. See if you can tolerate Samsung software after iPhone.
Good luck.
