Negima!: nice story adaptation until they thought LOL LET'S DO OUR OWN STORY ARC TO END THE SEASON. Ugly character design, too little fanservice, QUALITY. Shit sucks.
Negima?!: nice character design, okay animation, usual SHAFT stuff, script and characters completely rewritten and turned into Pani Poni Dash lite. Decent show, but it wasn't Negima at all.
