Started with a light weight strait cutter no-name Chinese thingy (Crowyman like) made from a flat plate. Too light, course adjustment, not great blade steel. Hated it. Got a Bench Dog. OK, now I had a good working tool. Don't care for the open throat but keep mine on a large extended base anyway. Then I got the K-M. I LOVE it. I would pick the Veritas second. Similar. I do like the canted knobs over the Stanly strait knobs ( L-N) Fit and finish of the Veritas is probably a tiny bit better than K-M, but we are talking a simple de-burr and tune. None perfect in my book. If I were designing, it would be a combination.
A new one is the Melbourne. Much cheaper, strait cutter rather than the hag's tooth. Worth a look maybe. If I were to buy again, it would be another K-M. I have not bought additional cutters. I was about to, but seems they have not restocked since the holidays. Lead times from China et. al. TayTools has one most like the Stanley, but expect a far rougher fit and finish and I have been a little skeptical about their blade steel not up to modern standards. Basically generic Chinese supplied. I would not an neither go for the E-bay ripoffs of the KM.
There are quite a few You-Tube discussions of the LN-KN-Veritas choice. Maybe a feature of one or another would ring a bell for you different than me. Unfortunately, you are a little far away so can't invite you to drop by and give mine a try. It comes down to personal feature choice as they are the top quality tools.
