Edward, nowadays most new better quality saws only take plain end blades. It's generally the cheaper saws that take pinned end blades, but, most of them now will take a plain end blade also. The quality of the saw, along with the quality of the blades will make a difference in the quality of your cutting. Plus, as others have mentioned, you need plain end blades to do fretwork and fine detail cuts. So yes, it's easier to load a pinned blade on your saw, but, if you only use pinned blades your missing out.
