I've been watching a few episodes of the Burst anime that I skipped in December or so and, real talk, Valt and Ben's battle is one of the best battles in the series so far. (Current favorites are Shu and Orochi's battle, Kensuke's battles in the Sword of Flames arc, and Xhaka and Wakiya's battle)
I think the reason I like the Burst anime as much as I do is because I like the characters. They're a lot of fun and I feel that if the writers of the show cared, they could probably make some really great episodes revolving around them.
The only thing the Animation has going for it is it's absolutely stellar CG. Most in-anime CG looks awkward and forced, but the various Beyblade animes have had pretty consistent and well-integrated CG.
for the most part (cough cough plastic gen)
Other than that though, the actual animation is just passable. I rewatched one episode of MFB recently (the ryuga and kyoya battle specifically), and the character animations are really good. I guess this could be chalked up to OLM still trying to find their footing with Burst, but when you compare the wonderful animation in the new Pokemon Sun/Moon anime, you'd think the quality of one would overlap with another, idk.
Overall, If the show had better writers and higher animation quality for the characters, the Burst anime would be an amazing slice-of-life anime with some amazing beyblade battles thrown in for good measure, which frankly is everything I want out of Burst
It also wouldn't hurt to have a better dub
