I can't speak for the other charger. But I've got a Battery Tender and it's outstanding. What I do like about the Battery Tender is that it's a 4 stage charger. I can't recall what all 4 stages do, but they are programmed in in order to correctly charge the battery according to it's voltage/capacity.

Pic below of the one I have. This one, due to its size, takes a little while to charge up a dead battery (4 days). But if you're just wanting to maintain your battery while you don't drive your car for an extended period, it's great.
