I dont see it as a Vortex trumps baskets issue but, a case of they simply work differently, the baskets are good for some things, the Vortex is really designed for very directed high heat (in the Narrow end up configuration). Baskets do an extremely fine job for keeping things divided for indirect cooking and when side by side, they will keep coals nicely unified but, since the cone is wider at the top the heat direction cannot be as intense as with the Vortex design. Its a matter of thermodynamics. I have no dog in the race but, they both have their advantages. You could dig the foundation for a condominium with a teaspoon but, if you have a back hoe, wouldnt it do the job better?
Nice illustrations of how the Vortex can be put to best advantage, Jeff. To tell the truth, beercan chicken just does not snap my cap but, a standing rib roast is another matter. Not being a Vortex owner, I cant speak to its effecacy, I do know that baskets do a fine job for that particular kind of cook, using the rotisserie or not.
