I have [this] (https://www.amazon.com/gp/product/B00MN0AO2Y/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) one for traveling because it seems more protected and [this] (https://www.amazon.com/dp/B00NHDFVEC/ref=dp_cerb_1) one for school because it's not as thick.
I didn't like the Nvidia case because it only protects the front and was too expensive.
I been using the Infiland case I got last year. It has the Pen hole so it was designed for the original Shield Tablet but its been just fine for me.
