The 26 gives you more real estate and more space for charcoal, particularly the newer version which has a larger charcoal grate. You could fit more stuff in there and still have room to keep it away from the coals.
Another alternative for a sort of indirect cooking is the mini-WSM. with the water pan left out, I often cook on the top grate which puts some distance between the food and fire. It's a kind of hybrid between direct and indirect. Of course it will not hold a 20 lb turkey like the 26.
Another alternative (which I have not tried) would be a rotisserie ring. There must be some way to elevate a grate in that to provide some additional space between fire and food.
