Depending on the type of accident.
1. If in an accident there is a rupture to the gasoline tank it can blow up and the car caught in a sea of fire make it difficult to escape.
2. Same situation with hydrogen if the hole is big there is no explosion or fire as hydrogen is very light and speeds up into the air. 12 cubic meters of hydrogen are for air one cubic meter is 1.22 kg give or take
3. If the leak is small in a hydrogen tank in all likelihood there will be a big explosion if the gas accumulated in the car, but no lasting fire, but not always IMHO
4. If the leak is small in a gasoline tank there will be a fire but it can be extinguish relative fast

All 4 scenarios are very specific and I will not keep them as guidance in buying a car as rarely a fuel tank is hit in regular road accidents.
