Mil Spec

Which one of these mil-spec phones are MORE durable?

The At&t Samsung Rugby…or the Verizon, Casio Boulder?
they’re both mil-spec..but which one can last through the toughest jobs?
and i know they both have navigation..but do you have to pay for that? does it come with the phone. or do you have to have it on your plan?
thanks for your help!!

My husband has the casio boulder and it has survived fire! he was a wildland firefighter before he left for BCT and his casio survived multiple wildfires in California over the summer. The navigation is $10 extra per month but gives turn by turn voice command and is really awesome. I would totally recommend the phone. However, I would also suggest the extended life battery due to all of it’s features and capabilities… it tends to die faster with the OEM battery. The extended life battery is $40 i think.
