I'd rate Sanford and Tampa as the same. Both have little international traffic so you tend to be the only plane in immigration so this tends to be pain free. Both have easy access to car rental. Sanford is arguablly nearer but the difference is small.
Tampa has better facilites when leaving BEFORE you go through security but probably worse than Sanford after security . Although Sanford is very expensive past security.

So from a landing experience and journey they are similar. Personally love Tampa as I tend to be on the gulf by the end of my hols so its nice and near. Nothing worse than driving past TPA on the way to MCO or Sanford.
