I'm not entirely sure I can label the DiC dub as "inferior" and my reasons are summed up in this video rather well:
Of course with me, I've stated how much of a fan I am of the DiC dub plenty of times. I can't deny nostalgia has some stakes in it, but I've said it before and I'll say it again. I find the DiC dub music just better than what the original had. In just about every way. I want THAT music.
If I was super rich and super lucky (as I'm sure it'd be a nightmare to get this done) I'd take the show, re-dub it with as close as I could get with the DiC voices. (Most notably as close as I could get for Terri Hawkes Serena. She'll always be my Serena) This includes the Fawk British Amy and Luna and all., but with nothing cut out. No cut episodes, no edited-out stuff, no mashed together final two season 1 episodes. (and no cousins, but that was another team entirely)
Sadly that will never happen, so I have to take what I can get. Luckily I DO have the original DiC Dub DVDS, and the Cloverway DVDS of S and SuperS, so I at least get to keep the names I was used to.
I grabbed Stars via the viz dub just to finish the series, and I have to say by then I feel the Viz actors have at least gotten the hang of it by then. Still not the biggest fan of them, but I don't hate it. They at least sound better then they did in the very first episode of the series. I'm sorry but to me that sounded like very wooden acting from the viz dub over.
Haven't grabbed anything else from viz yet. I will at least get the first season so I can watch the cut episodes and full two episode final.
