I agree, MCO has drastically improved security processing, however, MOST of the time, PreCheck is still faster.
One caveat re: PreCheck at MCO -- be sure that you get in the right line entrance. MCO also still has CLEAR, and I very often see travelers get into the wrong line and have to go back to the end again after they get to the ID check. At MCO, the PreCheck line entrance is rather hard to see, as it is up against an escalator wall. This is a photo of the A-side checkpoint for Concourses 2 & 4 (gates 70-129). The arrow shows where the PreCheck line now is located. If you are coming in from the A-side entrance headed for those gates, the correct line entrance for PreCheck is at the very far end of the security area.
