In looking at the specs for the two bikes, I don't really see anything that would give one the advantage of the other. Hence, I think what others have said is the unfortunate reality. An office premise test ride is probably your best bet. Is it possible to do some searching for shops that would allow such a test ride?
BTW, I wouldn't worry about where the bikes are made. Both companies have their reputations on the line. So, at this price point, you're going to see pretty much the same level of quality all around.
