I use nothing but a pop-up. Tree stands can be un safe because most folks don't do routine inspections, and they are dangerous even with safety devices. (read I'm afraid of heights) Tripods just don't give enough concealment with enough room to freely move as needed. And pop-ups can be moved quickly with minimal effort. And lastly treestands and tripods can be mizerable in inclimate weather. Pop-ups can be bone dry and you can even use a heater if needed.
