All of them are great imo, even Dave B. Mitchell (since he improved in Frontiers.) However I’d have to go with the best one of all 5 of them being Idris Elba, who’s my 2nd favorite Knuckles voice actor behind Scott Dreier.
@@Sonic.Primal6524 Me three. Those two made Knuckles (from both Sonic X and Boom) our favorites. Dan for how he put serious and quirky humor to Knuckles while Travis put his silly and goofball-like antics to Boom Knuckles.
Imo Idris Elba outranks all the voice actors for Knuckles. He's the GOAT (greatest of all time) and the perfect VA choice for Knuckles for the Sonic 2 Movie. Vincent Tong does a good job but Idris Elba is who I prefer.
Idirs Elba is great as Knuckles, but he will always be Heimdall in the Marvel Cinematic Universe, and as, Bloodsport in the DC Extended Universe, too. As well as that, he did create a British comedy series for Sky called In the Long Run, which stars my brother's friend from his school in.
