Ok I am going to go against the grain here...this thread gets the same sort of answer all the time so here is my anti BF answer.
Get the one that fits the worst and you will have to make the most adjustments to so that you will be as uncomfortable as possible. Also if there are two that are equally a bad fit get the cheaper and/or uglier one. Once you pick the bike that fits the worst and you know your size...make sure to buy some other size...fit is really overrated, you can't REALLY get comfortable on a bike anyway.
Then paint it hot pink.
Sorry but I wanted to be the first in BF history to ever have given that answer.

Just get the Orbea you know you want it.
