what do 你 think is better negima the book 或者 negima the 显示

I think the book because it has 更多 action and its really interesting.

the book, the 显示 pales in comparison.

The one I saw was a complete mess. It started out good, 由 following the basic storyline of the book, only in 随意 order and with small changes.
That is, until about halfway, when they started making big changes (to fulfill there own sick fantasies) and skiping important events from the book. They even skiped a, now major, character altogether. 由 the end, they had completly stoped following the book and made up there own storyline that was complete bullshit. And they even gave it the worst, most cliche villain ever: The Devil. (WHAT!?) There was never any mention 或者 even hint of The Devil before, why is he suddenly the main villain? It was so bad it was almost unwatchable.

Also, the book is still ongoing. So.... yeah.

I haven't read the 日本漫画 yet, but I have watched the 显示 and I like the 显示 a lot more. :D
