For most conditions, the climber would be my choice, followed by a lock-on, then a ladder stand.
If the trees will support a climber, its the best way to go!
Ladder stands are quickly accessed and quiet, but I have seen deer start patterning a ladder stand, just like they do box stands! They will look to see if someone is up there before comming out.
I know that happens because I have killed deer from a climber that was set up only a few yards from my empty ladder stand. I am convinced that had I been on the ladder stand, the deer would have never given me a shot!
