Android.
Although all android don't have a couple of the things I will list that I like over apple...
Removable Battery. This will come in handy later when I want to replace a battery for an older phone as I normally keep my older phones as backups even if just for the music.
Micro SD Cards aka expandable storage. Much Much cheaper to get a lot of extra room on an SD Card than paying ridiculous upgrade charges for larger spaces on phones out of the box. I also liked that my note 4 came with a base 32 gb storage vs my wife's Iphone 6+ with a base of 16.
The back button....it is a pain in the butt when I have to use the wife's iphone or her mothers when working on them. No back button argggg...you don't know how much I got used to using it on my phone.
Multiclear - When I click on my Tasks button on my android phone and it brings up all the apps running, I can clear all of them at once. I can do the same if I pull my screen down to my notifications area and I can clear all of my notifications at one time by hitting on button. IIRC I have to do those individually on the Iphone (unless it has changed) and with the way I have what I would call OCD when it comes to some things and those are one of them...I can't stand to see a phone with huge amounts of notifications that have not been cleaned off, Can't stand to see an inbox in someone's email program with the little numbers showing how many messages have not been read, notices and alert numbers on apps wear me out as well...just some quirk I have. So I like that the android lets me go in those areas real click and clean multiple ones off by hitting one button.
I can change the appearance of my icons with different icon packs. Can do the same with different packs for the look of my Clock and weather widgits on my phone as well.
Zedge - If I want a new ring tone or when I get board and just look for different ringtones and notifications tones, I can load up Zedge app, search and find ones I want and download them to my phone and set them. On the iphone now I have to get on the zedge app, it downloads the ones I want to my itunes account, I have to hook up my phone to the computer and connect it to Itunes and sync the ringtones to my phone...Sure it says it is a security measure but I have used zedge for years without issue and using it on iphone now is just a hassle.
New OS software delivery - this is both a good and bad thing with android compared to IOS. The bad is that Android users typically have to wait until not only their phone maker makes their updates or additions to the new OS but they also have to wait until the phone carrier to make their addtions or updates. So I have to wait for google to make the new IOS but I also have to wait for AT&T AND Samsung to do what they have to do before i get it. So other android phones might get the new OS months before I do or vice versa. IOS goes out pretty much at one time because they only deal of the iphone and not different makers and they go out at the same time for the different carriers. HOWEVER sometimes it is a good thing to wait instead of everybody getting at once as we saw some of the major troubles IOS had with that last big IOS upgrade and a few updates after. It screwed up some peoples abilities to do things and they basically had to fix the fixes to get them fixed. Andriod can have some of that but they are normally minor bugs that get fixed because most of the time most of the bugs have been fixed before they ever get to my phone.
