Short version: Nothing but a quad-pod for me. If my next PH doesn't have quad-pods, I'll insist he buy or borrow some before I get there...here's why...
The longer story: I practiced on "sticks" before I left for Africa. Since I didn't have any real sticks, I used a camera tripod with a gun clevis. Point being that this set-up only supports the forearm of the gun, not the buttstock. I was terrible and it worried me. I went back to the range several times and got a little better but knew it was going to be an issue. When I got to Africa my PH had quad-pods. We never lost sight of a single animal that I shot off of quad pods.
To each his own but I'm sold on the idea of a set of sticks that supports the forearm and buttstock. You pay your money and you take your chances. Lost game and lost time looking for lost game is the cost of not making a quality shot. Bored trackers is the benefit of making good shots. My tracker never tracked...at least not anything that was wounded.
