Worked for me

Only answer is: if he wants to.

I've never liked iOS' UX (do like Mac OS). Thus I've been with Android since the HTC Desire and now have a Nexus 6P. I think Android has really matured and is on par with iOS if you buy a flagship phone. It used to be great for people that like to tinker with their phones, but the out of the box experience is great now and you can change a lot by e.g. installing a different launcher and icon pack. My advise would be to do some research on all the OEM UI shells and don't blame Android for how much they (can) suck. Samsung has TouchWiz, HTC has Sense, Sony, LG, every brand has some sort of skin. Motorola only adds some useful tweaks, and the Nexus line is pure Android. The latter two have my preference and also update as soon as a new version is announced. Marshmallow is really nice, and coming from iPhone I don't think you'd like not having the latest updates. To wrap it up: please go to a phone store and check all brands out.
