As for that last part, I'm speaking from the fan's point of view since the show was under fire before its release and after the first season aired. It's true that nothing can beat the original classics since that's when the toons themselves were at their prime before the least successful revivals like Lunatics and the previously mentioned Looney Tunes Show happened. I do give the show credit for a few things like having Bugs beat Cecil Turtle for once in the life time (I've always felt that turtle should have been beaten one day whether it was in a race or not) and making Lola Bunny feel right at home since her Space Jam portrayal didn't feel all that "looney" to me (A flirty sporty rabbit doesn't feel like Looney Tunes material to begin with).
Hell yeah, One Piece is very diverse with its characters since 1997 thanks to Oda's unique artsyle. We can have characters that look cool (Zoro), wacky (Franky), serious (Akainu), sadistic (Doflamingo), cute (Chopper), chill (Kizaru), vain (Cavendish), badass (Bartolomeo), snobby (Ms. Merry Christmas), and weird (Chessmarimo). It's like one of these works that can keep a consistent story while having these quirky characters with their interesting personalities and laughs (No really, each character in question has their own unique laugh). There's Blackbeard's "Zehahahahahaha!", Perona's "Horohorohorohorohoro!", Moria's "Kishishisishishsihshi!", Enel's "Yahahahahahahahaha!", Diamante's "Uhahahahahaha!", and so on making each character funny in their own way.
Say what Bobobo? You ma'am, get to me in the top of my "Cool List" for admitting that you read Bobobo-bobo-Bobo without seeing just the CN anime in the past. Shinsetsu (The manga's sequel) was where things got even better since they had new allies in the form of Gasser's magical girl sister and a psychotic anthopomophic koala, not to mention Gasser's new transformation Wicked King Heppokomaru.
