Another big difference is the geometry especially the chainstay length. The aurora has a chainstay of 17.3 whereas the LHT has 18.1. This measurement is critical to avoiding heel strike to the rear panniers. Also the wheelbase of the LHT is longer making a more stable ride. Trying to avoid heel strike on a bike with a shorter than desired chainstay sucks, you always have to be conscious of it or you'll hit the rear panniers and possibily crash.
The aurora would make an excellent commuting bike to work. Looking at the geometry it looks like it would handle a bit faster than the LHT which is good in traffic. It can be a good loaded tourer with the right size panniers to avoid heel strike, but the LHT beats it almost every catagory geometrywise for carring heavy loads.
So, get the Aurora if your going to do light to moderate touring and commuting. Get the LHT if your going to do heavy fully loaded touring.
