I’m biased here because I already experienced the best iPad case in history (Anker’s Folio keyboard case) and this is the yardstick I measure everything against, but they don’t make it anymore.
This case fits nicely, I appreciate the rubberized interior for grip. The surface is pleasant and appears durable, but there are things to improve. The front flap can be stiffened more, if not made completely rigid, as that is the part that protects the screen. The edge flap that protects the camera has gaps in the glue, showing some bubbling when bent, and a magnet on the side edge that slots into the standing groove wouldn’t go amiss either - this iPad is very heavy and large and needs multiple levels of protection. The keyboard is sufficiently responsive and while I would prefer for it to be inset, it’s not a big hassle to remove it when necessary.
