What one perk do you really enjoy using?
I'm not talking about perks for a meta build, or to counter what you may consider 'against the rulebook' type perks, unless you just like the idea behind the perk itself. Just that one perk that feels fun to use, that reminds you that you're actually playing a game, and not just a sweat fest.
For me, it's Lightborn. Those extra few seconds where survivors are trying to blind, before it clicks that it isn't working, always makes me giggle. More so if they keep trying, either at another pallet, or backpedaling away from me as if I can't see them. I'll sometimes even let the flashlight user go, just because it's amusing to actually be able to use the perk for once.
Wish there were more perks like it out there.
