I have no experience with the Lahar, but I'm sure it would hold up very well. As I know the Endura would. So, from there it would be personal preference and comfort, I'd imagine. Both come in vg10 steel.
Would you prefer the "flipper" on the Kershaw, or the Spydie hole? I prefer the hole. The Lahar also seems to have a bit of recurve on the blade, some love it, some hate it, and it can be harder to sharpen depending on how you sharpen. Enduras fit my hand nicely, but the handle on the Kershaw appears to be very comfortable, though I've never actually handled it....
