I love having a stitch regulator, but keep it on "cruise" most of the time, at about 6%. This means the machine never completely stopped stitching unless you shut it off, but stitches very slow unless you are moving it., This way I can get an extra stitch in the corners if needed as I'm changing direction. I'll typically turn the cruise off when using rulers, and I have turned of the regulator when doing very tight stippling.
My bailey also had a stitch regulator, but it was a slow machine so I still had to be careful to move slowly so I didn't end up with long stitches.
