The thing is. You don't really realise how much attention you are paying to your cursor. Players who claim not to look at their cursor, do in fact know where it is and where it went last, and what they did to get it there. There is always a "check" process. It's how we learn and get better.
It is very much adaptation rather than find some settings and then "oh I can do that every time because they are the same and I used them forever"
- well no, you get better at learning how your peripheral moves, the angle deviation (thanks to logitech's video) and distances depending also upon the position of your hand and your grip... and that's why you get better the more you play with it.
If you had a robot hand that was bolted to your desk in one place, I'd agree with you. But you don't.
EDIT:
Anyway... the reason the OP is feeling like he can't play with either, is because he hasn't quite grasped the different movements with the tablet. But his brain has gotten used to the errors and is learning by adaptation. So when he goes back to the mouse he is expecting errors, but there are much less, and is compensating for errors which don't exist because of bad muscle memory with the tablet, which throws him off. Once he learns both he will find the differences getting less and less with time. But if you stick to one peripheral for a while and improve considerably, what you have learned has made you more consistent with that peripheral. Because you are now more consistent, your brain tries to compare the old feeling you once had, and thinks,"hmm, I sure as hell was more accurate with the mouse." The problem is that your prior reference point hasn't moved, but when you play it again... you think it has and feel like it has (for better or worse depending how good you were)... caused by getting better at using one peripheral and not the other. And let's not forget you got better at the game in the process.
Learning to play it though, in turn means you have greater control over your movements, since you've learned how to use some "neglected" muscles in your hand a bit better, with finer control. This works out as a positive either way.

I've gotten Insane FCs back-to-back switching play styles between songs before, if that means anything.
I also have back to back Insane FC's and I have completely different sensitivities. Point is, if I feel really "in-tune" with one, I play above my normal skill level. When I say I begin to suck with both, what I really mean is I mess up that feeling I had and return to being normal.
