Depends on what you want from a phone.
I have a samsung 4 and a Nokia Lumia 830
I use the lumia pure and simply because it is brilliant for texting. I press the mic and it understands almost every word I say, I then press 'send'
I hardly ever bothered with texts when I had to type them out.
I love my Blackberry but at over 4 years old it's coming to the end of its life and sadly that model is long discontinued. Never a problem with it, done everything I wanted it do, including a brilliant satnav and great for tethering my tablet.
I can even download library books to it.
I don't want an iPad for the same reason I don't want a Kindle.
