For me it depends on the situation.
For instance; earlier today I was killed by a one star and a two star fuling while out lox hunting. It happened very near to a portal I had just put up. All I did was top off my food, swig down a quick stamina mead and portaled back to the fight.

Another time I was out exploring the coast and was nearly a two day sail away from home when I got killed by a fuling after putting in to shore on a plains biome. They destroyed my portal so I had to fully gear up in my best spare equipment to do the two day corpse run.

Edit: That long corpse run is still one of the most epic and funnest adventures I've had in Valheim so far.
