Each has it's benefits. I tend to use my foot pedal mostly because I like to keep my hands on my fabric. My 1/4" seams are really inconsistent when I start moving my hands off the fabric as I get to the end of a seam. I really enjoy using the foot pedal for slow sewing then racing as I go down an easy seam. It's all about preferences. Like many others I am really enjoying the pressure foot lift when you stop sewing with the foot pedal. I'm not sure you have that function with the button. It's especially helpful with Paper Piecing.
