So far the Mora I bought to "try out" along with my BK2 has been my most used outdoors blade. As others have said they're not just an excellent value, they're also great designs, executed quite well.
I'll agree that they're tougher than you'd think. And personally I think they pair better with knives larger than an ESEE 6. I feel like the whole point of "robust" knives in the 4-6in range is to make it so they can be the ONLY cutting tool you take somewhere (with the Becker Bk16 being about as small as I consider that genre, and the ESEE 6 the upper end). If you decide to take multiple knives, one of which is a mora, I feel you should skip up and bring something appreciably larger, so there is less overlap in the "skill sets" of the knives you bring. That could be just me though.
My normal kit is a Corona folding saw, BK9, and Mora. Sometimes just the Mora and the saw. The BK16 I just got might start changing things though.
But it really is amazing how much value you can get from a Mora, a Tram machete, council tool axe, and a buck saw blade (or corona folding saw). There really isn't much you can't do with that set of tools, and even if you bought every one of those, you'd still be under $100.
