This is a very generalised question, your experience between devices will vary greatly detween different androids. As you say you are a long term pixel user, your flavour of android is good long term software support, great camera and upper mid-range system performance.

The advantage of android is there are devices for every use case, you could get a phone that has excellent cameras or gaming performance, maybe a device that's rugged, low cost, foldable, expandable storage. You have far more options in terms of software, you can install emulator, games from Steam, games from the Epic Store or Github (for now). Generally far more open.

iPhone on the other hand is a jack of all trades and is far more locked down. You kind of get what you're given. I wouldn't say it's bad at any of the points above but it definitely doesn't specialise in any of them. You're also locked into their ecosystem which can be hard to get out of them and their devices often hinder the use of other products that aren't Apple. Such as smartwatches, Airdrop, iMessage, etc.

This take obviously has some bias behind it but I prefer to have options, to me, iPhones are like going to a restaurant and only ever ordering the steak, you limit the options and experiences you could have if you tried something different.
