The dub for space dandy is so good, its on par with Death note and Cowboy Bebop(same creator as space dandy) dubs
Here is the synopsis
“Dandy is a fashionable space explorer on the hunt for aliens that have never been seen previously. For every new species Dandy discovers, he gets a significant reward. But he’s not the only one searching for the aliens, and he must be quick because alien hunting is a first come, first served profession. Helping Dandy on his intergalactic quest are his sidekicks, rundown robot QT and cat-looking space alien Meow. The best-dressed alien hunter in space explores unknown, alien-inhabited worlds on an adventure that ends at the edge of the universe.”
