Both 2 and 4 posts lifts have their advantages and disadvantages. 2 posts need to be securely bolted to the floor on an appropriate footing. Youtube is full of videos where the vehicle topples because the load of the vehicle got off the center of gravity and the lift wasn't secured. In my specific case the 4 post is a better option in that I wouldn't have to saw cut the slab, excavate for a footing and then refill with reinforced concrete and bolts. Also the 4 post can be moved if necessary. The 4 post with the jack tray also allows the raising of the wheels although as stated it is an extra step. Going up faster (220V) isn't an issue for me. I'm in no hurry to do anything anymore.
I have a 4-post, my son has a 2-post. I prefer the 4-post and I use a jack tray. Guess it just depends on what you like. I tend to use the tracks for tool and parts shelves while I'm working.
