Any regrets with the D800E vs D800?

We have both the D800 and D800E to serve as backups for each other and in case moire was an issue (it isn't.)

While I think the 'E' shows minutely crisper files it might be a result of the "placebo" effect and but not enough difference for even a moderately discerning eye.

We use the E for large print landscapes and the non-E for general street photography and in-studio portraits.
