WASD Keycaps and Filco OEM caps are pretty comparable to each other, neither are that good and will start to show shine relatively quickly with continued use. In terms of build quality, they're both very good, but many people, including myself, would probably still give Filco the edge. I would go with whichever you can get cheaper since you probably wouldn't notice any major difference between the two. WASD Keyboards come with a detachable cable, so that might be a little more convenient for you, but they'll both come with plate mounted switches.
