I have had a few different ones. I liked my original which I think was Teknic. It was very big and expanded enough that I could rest my chin on it. But the piping and zippers started to wear out and I could not find the same model. I made really good use of mine so their wearing out was not an issue that I could complain about. Really what you need to do is determine what your wants are. Size, pockets etc. Mine wear all magnetic and none of them ever slipped. The first one was both strap and magnetic. I trashed the straps. Edit. Here is my first bag.
