Story
As much I as I can glaze Oda, 2.5/5 of these stories aren't the best. These were probably Oda's first attempts at writing.
It is nice seeing Oda evolve his story telling. Though he shouldn't do one shots. Stick to long stories to fully expand the world.
Wanted was 100% the weakest of the 5. Either super inspired by Trigun or vice versa.
Future Present from God. The surprised enjoyed out of the 5. Didn't expect to like it.Death Note and Mirai Nikki before Death Note and Mirai Nikki. I liked the idea that God got One Guyed that he damned him to hell.
Ikki Yako. Ehh. Along the same lines as Wanted. Nothing cool story wise. Felt generic.
Monsters. This was a disappointment personally. I came in wanted this to be my 2nd favorite cause I've heard so much about it. Low and behold, called the story beats for beat. Though, it being canon within One Piece is pretty pog champ.
Romance Dawn. It's just One Piece. Romance Dawn walked so OP can run for 25+ years.
Art
Again, p goo. Cool seeing the art evolve within from the last story.
Wanted. Just like with the story aspect. The weakest of them all. Instead of Zoro with swords, we got Zoro with guns.
Future Present from God. A bit better then wanted. This is probably where Oda practice his big set piece battle that we love from him.
Ikki Yako. Let him cook, chat. This is getting way better. This is where we see more fisticuffs action. The character designs are probably the best out of these 5.
Monsters and Romance Dawn. It is just the character designs and art style of One Piece with a slight change here and there.
Overall
7/10, just proves that this is Oda's passion and happy we got 1131+ chapters from him
