As noted, they can have somewhat different fluxing power (e.g. nepheline and soda feldspar vitrify better than potash), but the differences are not great. It takes 35-40% feldspar to vitrify an American kaolin at cone 5-6, it is not practical to go much lower since there is not enough room in the recipe for the needed clay and silica.

Feldspar vs. Quartz: What's the Difference? 5 Crucial Signs
With feldspar and quartz, there is plenty of overlap between colors. Since they are both highly abundant crystals, there are plenty of variations. In many cases, though not always, feldspar is cloudy in appearance, while quartz is clear. If you held up a piece of quartz to a light source, the light would shine through.
