Hoist vs stacker
Well Rob a 4 post is better for storing a car.
Personally, I am a bit more comfortable working
under a car on a 4 post but either one works.
They both have advantages and disadvantages.
If you are doing suspension work or brakes,
really anything that requires the wheel off a two
post is really much more convenient by far.
I have one of each in our shops = I do not know how
I ever got by without them!
However, my Hobby has really gotten out of control the
last couple decades!
