I've got both the LN honing guide and the woodpeckers guide that they just
re-released as a one-time tool.
Because I'm not too far away from the LN office, I once had a chat with Deneb when I was in. (Side note: if you can ever make it, you should go! The showroom is a delight and my techniques have benefited so much from my visits there.) He's understandably proud of the LN guide. I also built their angle-setting station.
First on the guides: I use the LN for chisels, and the woodpeckers for larger plane irons. The single wheel on the LN makes it much easier to handle and you can use more of the stone because you don't have the wheel outriggers. The trade-off, though, is if you like to keep plane irons at 90º then the two wheels keeps you on autopilot more. They're more stable.
It's worth noting that if you like a bit of camber on some irons, which I do, then the single wheel of the LN guide is far superior.
And one more note: if you can get it still, the LN guide will not work with the woodpeckers angle-setting jig. The woodpeckers angle-setting jig only works with their honing guide. So while I don't use the LN angle-setting jig for holding stones or anything like that, I do still keep it around for setting the angle on the LN honing guide.
Happy to answer other questions if you've got 'em.
