Android Vs Blackberry OS which one is better

To me android is better than blackberry because of the following reasons (1) android phones can make calls on viber,blackberry can't make calls with it,they can only text (2) android play store is better of with applications than blackberry application world (3) android battery last longer than blackberry battery (4) android have gears than can be used with the phone,blackberry doesn't have any gear (5) blackberry sometimes suddenly reboot,android don't reboot
