When I got my first TE my excitement about trying it with Pac-Man CE quickly turned to disappointment. I just assumed an octogate was better for schmups to so never even bothered.
Whatever works best for you, sticks aren't going to make you suddendly perform superplays or anything. That said, once I tried a Seimitsu stick I never looked back, and my scores got better, if only because I practiced more with a stick.
