What’s an example of a perk on your hero(s) that’s situational and not completely shadowed by the other choice?

Many perk choices have one very obvious chocie that most players will always default to, regardless of matchup or map.

But, for example, Winston used to have the “short circuit” minor perk where he’d deal 50% more damage to turrets and barriers. obviously in some games, that was the worse perk.

what are some other examples?
