I'm just jumping into the conversation. I have a similar inseam and was told the 46 was best for me. I love my LHT! I just finished an eight day tour and really found my bike comfortable. The reach was perfect, my Brooks Flyer S saddle was awesome!! It is heavy but I kept up with two guys going 15 - 18 mph a lot. The LHT was very stable - I road down some hills going 34mph without feeling at all unstable and when I got out of the seat for some hill climbing it was good. Of course, I don't know anything about the other bikes. I do know I was thinking of a LHT or a Crosscheck and decided on the LHT because with my size it was the best fit.
Good luck.
