X-E1 vs X-pro1 how much better is EVF and Build quality?

Hi, with the recent price change in the X-Pro1 I am finding that the two models with a 35mm f1.4 is only a $100 difference. This makes the decision even tougher because I was set on the X-E1.

The main concern is the build quality. Is the X-pro1's build quality any better than the X-E1's build?

Also, how does the EVF of the X-E1 compare to the X-Pro1's? Is the X-Pro1's EVF still showing some lag even with V2.0 firmware update?
