iOS.
As an OS I can't claim that the capability is better in one or the other. But generally speaking apple does a better job of supporting devices longer compared to most android manufacturers. I don't see a point in switching phones every year. (each iPhone I've had, I've owned for 3 years, current phone will pass the 3 year mark in a month and this time I'm probably going to keep it another year).
At an subjective level apples ecosystem beats googles with a big margin. I prefer the closed environment with some QC than an open with almost no QC.
Also (since I don't use streaming services and have a big library of music accumulated over the years (a lot of the music I wan't simply isn't present in one single streaming service, this paired with that I rather only pay for the few new albums I get every year than paying for a subscription for music I mostly allready own)) apples music/ipod app is unbeatable.
