The class of the SD card doesn’t make that big of a difference from a speed/user experience perspective. You want a card with a high random r/w speed when an OS is on it. I suggest testing your cards with crystal disk mark, and use the one with the highest random speeds. It can make a huge difference depending on what speeds you are coming from/going to.
Here are a few card test results that were done on Raspberry PIs, but every batch of cards (even the same model) will have variance.
