I have this charger, it's a nice little unit, the "Dyno" is not really a dyno, just checks no load RPM, can weed out bad motors. The APS has a thermal cut off for charging as well (nice feature, just wrap the little thermal couple around the battery). The one thing I don't like about it, is the buttons are very hard to push. It has custom charge profiles, so once you set it up you can change profiles very quickly.
The ICE charger is a nice unit as well, it would be a toss up between the two. Windsorguy99 has an ICE charger, he could give you some more info on it.
