Will I gain much by moving up to the Toupe from the Alias?

I picked up an Alias from my LBS this past Saturday. I really wanted the Toupe but they didn't have my size (143). Beyond looks, I liked the extra flex compared to the Alias and the smoother finish instead of the two pads on the Alias (freer movement on the saddle).

I took the Alias out for a quick 20 miler on Saturday eve and 53 miles on Sunday. It seemed fine. I had a little pain in the sit bones on the long ride but I guess thats natural. The LBS offered to swap it when they get more Toupes. With this in mind, is it worth the extra $35-40 it would cost me to make the swap or is vanity getting the best of me?
