I don't believe you'd feel the slightest difference between the two bikes in the real world. However, for 10% more than you were planning on spending and a month and a half more wait, you can have the bike you really want. It comes down to being truly happy with the bike. If you save a couple of bucks but keep thinking of it as almost what you wanted, it really isn't worth it. The extra time and money will be forgotten this time next year but seeing the 6 on the side may bug you far longer. The fact you are looking for reassurance leads me to believe this will continue to bug you.
