Melancholy Of Haruhi Suzumiya has a dub that picked actors that sounded really similar to their Japanese counterparts and adapted a lot of the casual thoughts of the main character pretty well. I wish more dubs would hew closer to how they Japanese show does since that's usually the original version and they usually made their decisions for reasons pertinent to the show alongside the directors. I don't get why they feel the need to brag about not basing anything on the Japanese version outside the translation.
Also Vampire Hunter D Bloodlust since that was actually released in English first. There are a few other anime that actually got dubbed first. I hear Armitage III: Poly-Matrix has a good dub.
Also Ninja Robots Tobikage.
