The reason why this is interesting is that it seems every other Game with the word Kong in it has at least one top level Donkey Kong player in the top 2. Donkey Kong 3 Doesn't even have one.
Because Donkey Kong is so competitive I say the top 12 are definitely top level.
So let's look at the best players at the other Kong games.
Donkey Kong Junior has Mark Kiehl. Crazy Kong part 2 has Robbie Lakeman, and Wes Copeland.
DK2 has John McCurdy. Crazy Kong part 1 has Wes Copeland. Brazil Kong has John McCurdy.
The truth is it's always been this way too. Tim Sczerby, Billy Mitchell, Steve Wiebe, Ben Jos, and Hank Chien haven't even played Don't even have scores submitted. Dean Saglio, and Wes Copeland are the exceptions, but they quit at one million.
I have a feeling this will change in the future, but until then, it's interesting.
