Better capacity, but it also makes the tool heavier. If the smaller battery will get most jobs done on a single charge, not much reason to spend the extra money IMO. I feel that a 4Ah or 5Ah is the sweet spot between weight and capacity, but it does depend on the tool being used and how long it's being used for. I'd rather have two 4Ah batteries than one 9Ah.

Grabbed this one too. This thing is serious! Really like it. Makes you look like you are in the business too haha. But mostly because it is foldable. Initially I wasn't looking at foldable units, but I can just toss it in the car if I need to. Definitely worth looking at if on the fence.
