Someone on YouTube said he has a Mexican accent and now I can't unhear it. Like I never really expected the voice to be the same but whoever is doing the voice is making some strange choices.
Not an easy voice to immitate
The VA is Greg Baldwin. He voiced Aku before in 2009 for a Samurai Jack video game and also was the voice actor for Iroh in the final season of Avatar:TLA and Legend of Korra. It might not be perfect but at least they hired someone with experience in immitating Mako's work

I don't mind it but then again I grew up with the Dutch dub and only started watching the old seasons in English again when S5 was announced. I prefer this over the original plan at least which was finding an entirely new voice for Aku. They talk about it a bit in this video:
