Which lift is preferred (2 post or 4 post)?

So I am selling my house and I am leaving my 2 post lift and will be purchasing a lift at the new house. I wanted to get opinions on which lift is preferred by most members (2 post or 4 post). The lift I am leaving is a Directlift DL-9 with asymmetric arms which has been fantastic but it is kind of a pain positioning the arms when putting a car on there (I have a bad knee). I use my lift for repairing cars not for storage and was wondering which style lift you guys prefer.
