The cartoonish artsyle from the manga is contrasted by the more explicit gore and violence, which the anime toned down. So in the end it kind of balances out.
I should note that not all of his manga are like this, for Blue Strikers and HITS he only does the writing (possibly some input in panneling too) and leave the art for Makoto Sawa (artist for episode 3 end card).
