I tried both due to a lack of seats near outlets at West due to volume, and departure gate being closer to East. Ended up with nearly 4 hours due to early arrival and delayed departure so was nice to have a reason to wander. East is a disappointing mess but oddly wifi strength was better. Disappointing clubs for such a relatively nice airport.

As an aside, I found Denver's service to be better than reviews but no PreCheck for redeyes was annoying.
