Upgrading to Linear Rails a Waste of Money? - An Evidence Based Answer

Hey hey, I’m back after a few months of busy times. Today, we are looking at an often asked question in the world of hobbyist 3D printing. Are linear rails a worthwhile upgrade? There never seemed to be a clear majority when I looking this up, so, I decided I’d figure it out for myself. I hope you enjoy!
