Again, ignore the fact that iPhone is closed source

That's a big thing to ignore.

it does provide a infinite software update until it's broken

No, it provides a long (several year) life cycle, but Apple does EOL devices.

which is better service than most Android phone

Absolutely agreed.

even if considering installing ROM.

Less obvious; Apple probably beats many aftermarket ROMs on lifespan (while losing on other points), but it's a lot closer competition.
