I like the portability of the transit tripods but I think if you are looking for ultimate stability, the three or four legged large diameter pipe leg, heavy top tables are the best. The three leg type would give solid contact with the ground on all legs with no adjustment, but may leave the top canted depending on terrain. The four leg table will need adjustments on at least two legs to level it and be stabile. Just how stabile you need to be is the question... I'd sure like to test a surveyor tripod type at 1000 yards and see how much the crosshairs move on the target. A "V" top on an adjustable shooters stick under the buttstock could always be used to stabilize the rifle if needed though.
