AKV is our home resort. The first time we stayed there, we were not DVC'ers, never stayed at a deluxe. We booked a standard and were upgraded (2006). We were on the Uzima side (East side). We feel in love with the place and ended up buying in (See Disney, upgrades work!). Since then I have also had rooms on Arusha (center) and Sunset (west). I would rate them Arusha, Uzima, Sunset. I should add that when I had a Sunset view, it was club level, and we were so high up that the tree tops obstructed distant views. At Uzima, we were down low and could see across the whole area outside our room.
Let's say the price difference is 30 per night, and you are there a week. Personally, I would be more than fine with either of the others and keep the 200 bucks. At Jambo, there are many public viewing areas for Arusha, most with seating. Arusha is the most accessible savannah at the resort in fact.
Be sure and explore the resort while you are there. There are some great details.
