I was wondering which type of L.S.D. you would chose for your vehicle? And why? Anyone know of resources to look at comparing the different types?

I would look at two things:
1) What is available for your vehicle 2) What is the intended use.
If it's a Civic and you're road racing or autocrossing,a gear-type differential is the most universally liked. If you're rallying, however, you might want a clutch type that can deliver some power with a tire off the ground or a busted axle.
Well... the brown acid is not poisoned. It's just bad acid. But it's your trip, so do what you want.
That's like asking, "what kind of suspension would you put in your car?" It depends on too many variables: drivetrain layout, power, budget, how the car will be used, how much additional maintenance are you prepared to do.
As for comparing different types, there was an article in GRM several issues back (I forget which one) where they tested several different units in an S2000 on an Auto-x course.
Sorry I should have said I am designing it for a small human powered off-road vehicle.
If there's a chance you're going to be hanging a wheel, you don't want a helical gear type. They go open if you do that. What about simply running a spool? A bit of body english might help the creature turn and then you save the weight of a differential unit.
I'm guessing, if you decide to go with a diff, that you'll want to look at options from the ATV world.
I'm thinking lawn tractor / mower unit. Check out theses. https://www.surpluscenter.com/powerTrans.asp?UID=2009062918595348
they normal have some nice small units.

If it works out, will you be building a "biggie-sized" one for the larger humans who want to power an off-road vehicle?
On this application, I'd look at ball differentials like the ones used in R/C cars. Light, cheap and easy to build. It's not truly a limited slip, it works more like a helical gear setup. The problem with clutch type limited slips in an application like this is they develop a lot of drag. I'd think that would wear your operator out in a hurry.
