Having worked around both types, for doing any real work on the car I would go with the 2 post. The 4 post in my OP would be fine for general maintenance and storage but all those post and rails I find to be in the way. I took a look at some of the sites that sell the 4 post, you don't see many touted for working, most every one shows cars being stored. If you want to change tires or do brake work or ?, you then have to buy more "stuff/things" to lift the car up off the rails if it does not come with them. One site I looked at, those jacks run $800 to $1600 more over the cost of the lift. that may be the top end prices, I only check one.

I was just thinking about how nice it would be to have a 2 post lift today before I read this, wishing I had space for one for.
