Two post lifts make working on wheels and suspension parts along with exhaust easier. More costly to install. Require getting down on your knees to set the arms and setting the stand offs can be tricky at times. They require you to be more safety conscious.
Four post lifts can be free standing and easier to position the vehicle on. You have to be creative or purchase the air/hydrolic jacking attachment to get the wheels up for work. In my opinion they are safer for the hobby user.
I like my 4 post lift for the convienence of installing the wheels and moving it around as needed.
