I love my 3 and have put it through hell. I have used it for light prying, things like taking bark off a tree and digging through a stump, with no problems at all. I am not advocating you to go pry a crate apart with one but it can do a lot of different tasks. I do not have a HEST, its on the list, so I cannot speak to that but I do love my 3, it is a great overall knife. It is big enough to baton, I use it to break down bigger pieces into kindling, but small enough for good control while doing some carving and such. Plus the 3 is a great size for EDC, small and light but big enough for some serious work.
But then again you can't go wrong with any ESEE so buy what makes you happy, they will all get the job done.
