I think because it is relatively cheap compared to other solutions, it's pretty accurate, it's low friction, and I really like that it's open source. You can't compare it to commercial linear ways (too expensive) or plastic sliders on regular extrusions (not very accurate). It was a good replacement for the previous solution of gluing metal V rails to a regular extrusion.
