I always see folks hating on plexi, and never can figure out quite why. I use dark tinted (which replaced the original polycarbonate front window on my old defender cab) and it's been working out fine for the last 11 years. No noticeable scratches, and I have used window cleaner and paper towels to clean it many times. Just don't scrub at it with a really dry paper towel. I now use a micro fiber cloth as it picks up dust a lot better. I also don't have any "haze" at all after cleaning. If you smoke, or the cabinet is next to your kitchen, then I'd expect you might have more of this kind of thing (tar and grease sticks to everything).
Plexi is lighter, easier to work with, can be found easier, comes in more readily available colors and thicknesses, safer and is usually much less expensive. Nothing wrong with glass, but even many original cabinets on route went with polycarbonate, which is even softer and more prone to scratching.
Use what your preferences, availability and project requirements dictate. You can't really go wrong.
