I have a Detroit, but might try an Aussie if I were to do it again. The Aussie is less money and should be a bit smoother on the street, but it would make a lot more noise when ratcheting on the corners. LockRights are a similar design and notorious for their noise.
P.S. you forgot Detroit EZ, Toyota E-Locker, limited-slips which technically isn't a locker, but neither is an open differential that IS and option.
