Yeah, it really depends on the situation, and how many other people are fleeing an area. Overall I'd agree that an EV is probably better for many of the reasons listed here. However, there are other situations to consider.
If you run out of juice, your car is a brick on the side of the road. No one is coming by with a portable supercharger to help you. In an ICE car, someone COULD bring/loan you a couple gallons of gas, or you could walk to a gas station.
Right now there are super-long lines at gas stations during an emergency, but as EVs become more popular, there will be super long lines at chargers too (and charging is a whole lot slower). Living here in SoCal, there are already lines daily at most superchargers in San Diego and Los Angeles areas.
BUT, as others have pointed out, gas stations run out of gas during emergencies, whereas chargers will work as long as the power is working.
Now if you're talking Zombie Apocalypse-type emergency, then you gotta go with gas. You can find ways of pumping gas out of the underground tanks or other cars for quite some time until the gas all goes bad, but once the power is out, you aren't going to charge your EV (at least not without lightning and a clock tower)
