Can only give personal opinion from my experience.
Had a Blackberry, Androind and iPhone.
I still have the latter two.
I use the iPhone almost exclusively – it was just so intuitive, picked it up and started using it (bloke see, instructions are just litter!). Everything is just so easy to set up and use.
The Android is ok, just needed me to acquire a bit more knowledge to get it working as I want.
Blackberry, binned it ages ago – way too limited in so many aspects and once I go the iPhone there was no competition.
Downsides of the iPhone, as has been said – battery life can be a bit short if used hard and they do not bounce, not even gently. Fortunately there are loads of replacement front and rear glass and they are cheap as chips on ebay. It’s a simple job to swap if you are not totally ham fisted.
