Both are great, I slightly prefer the endura for a few reasons.
1. Longer handle allows me a full, extended, thumb on spine grip. This places the blade in perfect allignment with the thumb pad, wrist, and forearm muscles. Blade point lands where I look, very controlled grip with a ton of reach.
2. Looks, IMO, better than the Stretch. Not that the Stretch is ugly, I just like Endura's look more
3. Little bit thicker and stiffer blade, talking about stock thickness and grind. The Stretch does cut better, but I didn't notice a huge difference in general use. The Endura's grind is just more durable without sacrificing much in cutting ability.
4. Price. Endura is cheaper in every style
