I came real, real close to buying the factory built Limmers about 15 years ago. In fact, I did buy them and then returned them in favor of a pair of Merrell Wildnesseseses.
From a value point of view, it was a horrible decision. The Merrell's completely fell apart due to the new fangled lightweight foam mid sole they were originally built with. The Limmers, of course, use traditional heavy leather mid soles.
But from a fit and performance point of view, I think I made the right choice. First, unless you are talking about the custom Limmers, there is no universal "best" when it comes to fit. It's all about finding a match between the factory's last and your foot.
Second, it seemed to me that the Limmers are fairly low cut in the ankle. I have loose ligaments and am prone to ankle sprains (and other related injuries) so I greatly prefer a slightly, more supportive boot in the ankle area. I finally retired my Merrells and am currently in a pair of Fabiano Rios, which are even higher. BIG NOTE: Ankle support is NOT the sort of thing where more is better, as a rule. Too much support hinders easy walking and I'm sure the Limmers provide enough support for many, many people. Just pointing out what I found to be a distinguishing feature.
I'm a huge fan of tradition norwegian welted boots and would own a pair of custom Limmers if I could afford them.
