Never heard of any of these phones actually but have personally used the top of the line Galaxy S series phones for many years and the older ones still get regular security updates. S7, S8 and S9 in particular have been distinctly superior to iPhones - I personally found iPhones to be very clunky virtually unusable compared to these.
