My classic go-to’s are usually DBZ/DBS, Cowboy Bebop, Space Dandy, Samurai Champloo, FMA:B, and Trigun. Some people like the Jojo and HxH dubs but I’ve only ever watched them subbed.

I thought the AoT dub was decent, but it’s AoT and therefore you shouldn’t watch it lol

If you’re looking for movies, the Ghibli catalogue usually have very good dubs. I’m a fan of the Princess Mononoke and Porco Rosso dubs myself.
