What are the best gun buddies in the game?

Recently, my brother discovered I had the VCT 2021 Spark buddy on the Prime Vandal, which essentially looks like what a pro could use at an event, so he's been begging for me to drop it after we both agreed that it's probably one of the best buddies in the entire game.

Obviously, there's also the Fist Bump (Riot) buddy, but what are the best buddies in the game in your opinion? I'm curious to see what people think...
