I have both. I believe it depends on your use. If you want a holster for outdoor field use, where you may be subject to woods use, and may want a little more protection I would choose the Simply Rugged. If you want a CCW holster, I would choose the Lobo. Both are very good, the Lobo is more "molded" to the gun but less leather to clear when drawing, the Simply Rugged has more leather higher up on the gun for more protection and great retention.
