I was checking out both of those myself recently. If you check on Music123.com you can see some of the reviews. And as always don't forget the reviews on HarmonyCentral.com I was thinking about trying the HFH in the bridge on one of my guitars just to see how over the top it can really be. Truthfully I haven't really heard anything bad about the evolution pickup. It seems to get talked about in every forum I've visited.
