Dragonheart is one of my favorites from childhood, and although Draco sticks out like a sore thumb, the soundtrack is still stellar, and the dialogue is witty as fuck, I never caught on to it as a kid and I love it.
4KIDS' dubs are hit and miss, of course, but one thing I've noticed when I got older is the dialogue in nearly all of their dubs is really snappy (and full of innuendoes), and I get a lot of lols from watching them when I want a pick-me-upper. Pokémon I think still holds up as one of their better dubs (and honestly just a good kids' show in general, there was heart in early Pokémon), Yu-Gi-Oh has produced memes like crazy, and for a "so bad, it's good" dub, Kirby: Right Back At Ya! has allowed Ted Lewis to shine with his King Dedede and Escargoon performances (Paul Lynde impressions are the greatest). But about a couple of years ago I decided to give Ultimate Muscle another shot (wasn't really into it as a kid, kinda grossed me out a bit), and holy shit it's pure gold, I can't believe I didn't appreciate it back then. The shit they got away with is amazing.
Also 4KIDS produced TMNT 2003, which yeah fell in quality around season five/six, but it's still fucking awesome.
Despite what a lot of the fanbase says, I also appreciate Saban's dub of Digimon a lot for being similar to 4KIDS in terms of dialogue but it didn't treat its audience like idiots (still wonder about the movie, though, but there's still awesome moments to be had). Unlike with 4KIDS who (usually) dumbed down mature subjects brought up in its shows, while Saban kinda beat around the bush in some aspects, they still tackled it head-on. It was quite impressive for a 90s kids' show to have characters (and kid characters, too) being confronted with divorce and adoption without being moralfags about it. Now given that Japan handles such subjects IRL differently from Western society, the gut-punch isn't as strong in the dub, but it's still there. I mean come on, where else are you going to have a character's parents have a talk with their son about his adoption and bring up the heavy implication of miscarriage or just their baby dying in general?
Oh, and Digimon was one of the few kids' shows that showed the parents being involved in their children's lives and being human. Also has one of the most awesome parents in fiction (or just in all of Digimon) in Hiroaki Ishida. The fanbase didn't turn him into a memetic badass for no reason.
If I think of anything else, I'll post again, 'tis spergy enough as-is.
