Most companies who say they use extra thick edges are using the same standard edge thickness seen in most brands across the industry (making the statement the same marketing BS featured throughout this thread).  That standard edge corresponds to base that is generally about 1.2mm to 1.3mm thick.  In almost all cases, the thickness never goes over that (and is often times is thinner).  So a lot of times when you see companies talk about their 1.8mm or 2.2mm or 2.5mm thick edges, they number they are putting out is the edge width, not the edge thickness (which is rarely included), which remains the standard thickness as it related to a 1.3mm thick base.  While a wider edge is going to provide a bit more durability than a thinner edge as it pertains to real use, it doesn't increase the durability of the ski on rails nearly as much as increasing the edge thickness.
Hardly anyone does this, as it adds considerable weight, cost, and manufacturing difficulty to increase the edge and base thickness.
The only companies I know of actually using a 
thicker edge (and thicker base material) are ON3P, J-Skis, Kitten Factory, and Batalla (I believe).  There are probably a couple more, but not many.  From what our supplier has told us, the edge we all use has its origin in helping to build rental fleets, where the ability to grind the ski over and over and over while maintaining usable base & edge thickness is a key component of making the rental skis very profitable over the long term.  When we started sourcing our material back in 2008, I told our supplier I want the absolute biggest edge we can get, and that is what ON3P and several other brands are using today.
So, by comparison, the brands I listed above are all using a 2.5mm wide x 2.5mm thick edge, with a 1.8mm thick base.  A lot of the brands that list their edges as "2.2mm" or whatever are using edges that are 2.2mm wide x 2.0mm thick, with a 1.3mm thick base.  That extra 0.5mm of edge is considerable and gets you a lot of extra life out of your skis.
There is a good thread from awhile back that featured a good discussion on edges.  You can see it here.

Here is a image from our supplier to give you an idea of how the edge profile actually looks, and what sort of variation you can get.
For what it is worth, we've looked into getting even thicker and wider edges, but the order requirements for full on custom edges are over what we are able to afford at this time.
Hope that helps.
