That style is great, but the Klein or Irwin branded versions are on the shelf at your nearest big box for less money.
Agreed; I think this style works even better, especially for stranded, and it's more convenient for getting into small spaces for vehicle wiring. Again, there are tons of brands selling the same thing.
Or, do the usual GJ thing and buy both, and see which you prefer.
I'm not a fan of this style, because you have to carefully choose the correct hole for the wire gauge you're working with, which is mistake-prone and slows you down. They do work great, and sever the insulation cleanly. But when visibility and access are poor, they're a lot more difficult to use, and you'll probably get the wire in the wrong hole more than once and damage the conductor, and have to cut it off and start over.
