Nexus 4 versus Google edition Galaxy S4, what to buy? (Read first)

Before you go, a couple things to take out.

1. Money is out of this comparison. Sure, it is something that may decide a purchase, but in this case, i would like it to be a non-factor. Suppose you have the $700 to buy the S4 or the N4 and no other immediate need or want to splurge it on.

2. Build quality is also out of this comparison. Again, it is another area which could make a decision, but suppose you are going to put the same case on either.

With those two out (for people who don't care about the two factors there), which of the two phones do you think is a better buy and why?
