I have a 2 post. Buddy has 3 4-posts, and swears by them. Bro-in-law has a new shop and looking into which lift. My feelings after all this, 2-post is cheaper, most things are easier on a 2 post. You have to get on your knees to set the arms. 2-posts are not portable, plan on loosing some shop space. 4-post with the nice air jack options are more costly. They are portable with the wheel kits, easier to put a vehicle in the air. Put take up more shop space meaning their foot-print. I do put a car on mine and store one underneath when necessary.
