To get one thing out of the way, if you take Bobobo seriously you're doing it completely wrong. It's a comedy manga. The fact that Bobobo fights with nosehair, that Don Patch is an orange... something, etc should be taken with a "haha oh wow" attitude and if you don't you're incredibly stupid and ruining the enjoyment the manga. The story goes well with the humoristic theme of the series and the characters are all fleshed out in their own hilarious way. I laughed all the time as I read it. Fans of YGO and DBZ should also be able to appreciate the various parodies on these and other mangas.
As far as the art goes, it goes very well with the silliness in the manga. Compared to other manga it's kinda mediocre, but when combined with the extreme humour of this series it fits amazingly well.
If you want something incredibly funny and not too serious Bobobo would definietly fit that request. Absolutely recommended.
