Android simply because of the freedom.
I can't stand my wife's iPhone (currently on XR), Apple Watch, or my son's iPad (we got it originally for his speech delay). The UI is garbage. The Settings menu is the biggest shithole imaginable. The updates...OMG don't even get me started on how horrible those are in terms of length of install time.
And the abomination that is iMessage is the king of the shit pile. Not because it isn't a good product (it's a actually a very good messaging system), but because there's no way to NOT fucking use it if you don't want to. iMessage is why I still have Apple crap in my house. I can't get my wife completely off it without killing the entire Apple account which would then cripple my sons iPad (he's only 7). What happens is iMessage ties to your phone number AND your email address without asking. Apple just opts you in. So even when you de-register the phone number the email address with iMessage stays active. So when we tried to move the wife to Android all her group chats with her lady friends (all on iPhones) got missed. iMessage still saw her as an active user because of the email address tied to the account. There is NO way to remove that link meaning locked into ecosystem unless we delete and start over. Total horseshit.
Especially now days when iPhone camera isn't the best anymore, the only reasons to buy an iPhone are reliability, support, and resale value. Lord knows the iOS UI's 3x3 foldering system and lack of app drawer is just ancient...
I got a XR because of the price. I'm sorry, Apple, but Android flagships have been using OLED displays for years and they aren't (weren't) charging $1000. The XR should also have an excellent resale value and should get just as much support and updates. So this extra charge Apple is charging for OLED is frigging ridiculous.
I see some good in aspects of Apple products but I really do not like the company or their end products. Android has a lot of issues but I have enjoyed it immensely.
I don't know that I'd object to Apple given Google's own practices. I don't think Google is evil incarnate, but it did strong-arm phone manufacturers and had to be browbeaten into paying a modest amount of respect to privacy. And don't get me started on its piss-poor attitude toward security updates.
The reality is that neither company is particularly grand, although I lean toward Apple simply because it makes some principled stands that Google doesn't.
Another thing. iOS generally have better 3rd party app support, except in a few categories.
1. Keyboard and password manager
2. Phone caller ID/spam blocker
You forgot to put *Fight* in the thread title. /j I think the iPhone is very simple and because of that simplicity, it just works. However, I use Android because of straight up cost of the phones, more than anything else.
Prices are getting insane. When a flagship was $500-600, it was an easy purchase to make 1-2 times per year... now that we're north of $1k for a flagship phone, that's now price competitive with decent laptops, LTE tablets, etc. It's no longer an essentially impulse buy because "oohh, shiny!" and smartphone sales (Android and Apple) have been falling, likely due to the higher and higher prices. I'm not sure who Samsung things is going to buy a $2k folding phone/tablet- I know I'm not since sales volumes will be thin, and therefore they'll support it for a year and end support- just like they do with every other low volume device like their fridges, tablets, etc.
