I do not have the Fehrman, but I do have 2 ESEE-5's (one partially serrated, one plain-edge).
To me, the ESEE-5's just fit perfectly in your hands. Its handles are great, and when you hold the knife, it just feels right. There's heft to it, you know it will stand up to almost ANYTHING you put it up against, and the heft helps with any chopping tasks. But the weight is not overwhelming.
I thought I would miss a finger choil on the 5, but surprisingly, I don't anymore. The rougher canvas micarta on the handle gives you really good traction and grip even when wet, and even though it lacks any "designer grippy/traction treads" machined into the scales, I am very confident that the 5 will always stay in my grip. The semi-sharpened pommel is also a very nice feature. The jimping on the spine is also very well placed, and is comfortable, yet grippy. The 1095 is a no non-sense great steel. It's easy to sharpen (from what I can tell so far), and keeps an edge pretty good. And at a 1/4" thick, you've got yourself a VERY sturdy knife. I don't think I will ever hesitate to use it to pry things, or wedge it into something and use as an impromptu step, and I weigh over 200 lbs.
I have recently acquired a ZT-0100 in 3V steel, but have not yet been able to really put it through its paces. Like anything else, Harder may mean keeping an edge longer, but also means harder to sharpen. I do think the canvas micarta on the ESEE-5 will give you a better grip than the linen micarta of the Last Chance, but the linen micarta may be smoother and look better. Do you need its extra strength over the 1/4" 1095? The 3V may take a rifle round better than the 1095, but... is that more important to you than the ease of edge maintenance? The 3V knife may make a better pry-bar. It is 1oz lighter than the ESEE-5. It's also $100 more than the ESEE, and the sheath costs extra ($25?) still.
It's a personal choice, but I think I would prefer the ESEE-5 simply because it's built like a tank, and its edge is still going to be easier to maintain. Did I also mention ESEE knives' unbeatable warranty?
