I prefer non stitched but it depends on a few things. I use a low sens and stitched edges limit the amount of room particularly on height where some times I want to slightly over run the pad. Also I hang the edge of the pad slightly off the desk so it's more comfortable on my arm. Stitched edges are good if you are constantly rubbing the edges
Also the cheaper the pad the worse the stitching tends to be being less tight and more raised. Don't expect gsr or artisan levels on this pad. It's alright for the price
