I had some issues with how this turned out. I am okay with Flashpoint Batman defeating Killmonger, however, the set up didn't make much sense, and Flashpoint Batman should've really been messed up after the fight was done. Killmonger should've taken Batman to his limits. He should barely be standing after a fight with him.
But from jump, it made no sense that Killmonger would be after Batman. Especially when they later show he has already become the Black Panther. Batman is too small fry for him.
I did think a lot of the costuming and some of the special effects were on point. In the discussion afterward I hadn't considered it a battle between magic (Amazonian sword) and science (Killmonger's tech) while watching it. Though it shows that they story took liberties here as well. We are to assume that Batman would know what kind of weapons and poisons would work on Killmonger. So you have to go with the Batman is always prepared logic, which then you have to accept that every Batman, in basically every reality, is prepared since Flashpoint Batman is Thomas Wayne and not Bruce. And Flashpoint Batman uses guns. He doesn't seem as good as Bruce, from what I recall of the Flashpoint Batman story, which is not a lot to be honest, outside of him using guns, him owning a casino,

the twist with Martha Wayne, and the letter he writes to the Earth-1 Bruce (which is later revisited in the Flash/Batman crossover "The Button")
. That being said, he's still Batman, so he's going to be pretty good regardless. And I have not read all of the stories with Flashpoint Batman so I could be missing something. Granted, I haven't read all the stories with Killmonger either.
During the discussion, it feels they brought Damion Poitier in to back up the results here, and while he accepted them, he wasn't fully on board with it and I was glad for that. I could just as easily seen this fight going to Killmonger. He's younger, faster, superhuman (due to the herb, but even before he ingested it he defeated T'Challa who had the herb), and even more ruthless than Flashpoint Batman and arguably just as smart, or smarter. Of course if you have this as a vote, the legion of Batman fans are not going to go with almost anyone defeating any Batman, until DC unveils their black Batman next year (if they go through with it). We'll see how much he gets owned in the comics and as well in online matchups.
