I'm not familiar with the OGR stripper; so my comments are based only on wire strippers I own. I have five pairs of good to very good strippers that I have used for a variety of projects including train wiring, but several years ago I picked up a pair of Xuron stranded wire strippers at a train show. I find them superior for high gauge (small diameter) wire stripping. They have excellent touch-feel for delicate work as they are smaller than most strippers, and they have sharp cutting edges. They are a finely crafted product.
Xuron strippers come in three flavors all with cams for different settings: continuously variable, notched for stranded, and notched for solid. Last year I picked up two more pairs from Micro Mark (#86701 continuously adjustable, #86709 for solid) so I would have the complete set of three. Since stranded and solid have identical notches but differ by one setting or two gauges (18=20,20=22, et cetera), one notched set can serve both purposes, but require careful mental bookkeeping to keep straight which is the correct gauge setting on the tool.
Now as for the continuously variable set, I find them extremely useful for very fine wire such as 30 gauge that is often used with low amperage LEDs. Also I have found I can more carefully avoid nicking wire. At about $16 a pair it could seem like a waste of money, but for me, they have made the tasks easier and more enjoyable.
