Anime with good English dub?

Nana

Monster
Moriarty the Patriot
Might as well pick something from your planning.

Reincarnated as a slime and Haikyuu are my personal favorite dubs, you might also like it

Code Geass Lelouch of the Rebellion

Gankutsuou The Count of Monte Cristo
Space Dandy
MUSHISHI
Fruits Basket 2019

Try gungrave, It has a really good dub voice over

Even Blue Gender is really good

Both of them i mentioned are some old classics

Definitely don't give up on English dub. There are plenty out there that are just as good and even better than the sub (I watch both). Here's my list; I'll try and avoid anime you've seen and anime I've only heard one language of to keep it unbiased.

Dub > Sub:

• Cowboy Bebop(I see you just started that)
• Neon Genesis Evangelion(Netflix)
• Yu Yu Hakusho: Ghostfiles

Dub = Sub:

• The Eminence in Shadow
• 86
• Gurren Lagann

However, these are some of my favorite dubs if you ever plan to rewatch these series: Kaguya-sama, Frieren, Violet Evergarden, Re:ZERO, Cyberpunk: Edgerunners, Black Clover.

It seems you dropped it, so probably not worth recommending it to you… but Baccano has a great dub!
Baccano

Some of my favorites off the top of my head:

-Saiki K. season 1
-Kill la Kill
-Toradora!
-Black Lagoon (the most I've ever heard these Canadians swear, lol)

Yu Yu Hakusho. A classic and the English dub is better than the japanese

Dub > Sub:
Berserk
Cowboy Bebop

Dub = Sub:
Girls Last Tour
