Deep down, I think a lot of people like to focus as specifically on a character as possible to toss out as many dissenting opinions as possible
Now granted, there are times where I won't vote when I feel I'm not familiar enough with the character as a whole, but that would be the case when they're in different mediums or not. Like I abstained on Vegeta despite having enough familiarity with his character to give him a vote due to lack of familiarity on his primary source material (base DBZ). Negan I feel more or less okay with just dropping a vote, though, particularly when Scarlet has the exact same problem with the comic character (overstaying his welcome) that I have with the show character.
Like for another example we've already voted on, Bowser. I think he gains a ton out of the Mario & Luigi series. I doubt literally
every
Bowser voter had experience with that. I strongly suspect there are more differences between M&L vs Standard Bowser than Comic vs Show Negan, despite being in the same medium, but no one would suggest splitting Bowser votes.
So yeah long story short I don't think it's important to isolate mediums. Not really.
No problem!
This is a cute and pop genocide of love!
