I personally prefer the lever type. I had a customer come in one time with an overheating engine, and I went to loosen the cap after running water on it. It turned out to be almost off, and the small amount of turning I did let the cap all the way off. Hot coolant shot all over my face. I quickly turned the hose on my face to take the heat away. Not even a blister. I was really lucky not to have been blinded.
