OK, if you say so, I'll take your word.
But let me just ask one thing: Do you work with paths, either in Photoshop or Illustrator? Are you able to hit handle control points, with confidence, every time? If you can, then your neurons must be wired differently than mine, because I can't. But I can with a mouse.
I did try for the longest time, because I really believed the dogma that tablet is king and mouse a poor man's substitute. I even put the mouse away for a week or two, just to force the issue. But instead of getting used to it, my frustration only grew, and in the end I said **** this, I have work to do.
Aside from the fact that the pen tip moves sideways as it moves down, what I miss with the pen is resistance, inertia or whatever you should call it. If you could dip the pen in heavy grease it might work...
My hands aren't particularly unsteady; it's just a physical property the mouse has and the pen doesn't that I'm much more comfortable with.
