I've never been that big on comas because you don't get two-way interaction till they come out of it. Though I do like the coming out part. Especially when someone's been sitting by their bedside until they've fallen asleep, or has been sitting there for days while barely eating. But you can get that without a coma per se.

TBH I think I got burned out on comas due to them being SO common in 80s TV - I hit the point where I would start giggling whenever some doctor solemnly said about yet another character, "They are in a COMA."

I have however never ever gotten burned out on gunshot wounds. Especially if they were received by jumping in front of someone.
