Well, I've played a few, but probably not as many as people would think. (which may now negate all the praise I just gave Last Hope

)
I've played a few to the extend of getting at least close to halfway through (Not counting anything "manic"):
Metal Black (Awesome)
Gradius V
Zed Blade (Aww yeah, so awesome)
Sexy Parodius
Darius Gaiden
Macross: Scrambled Valkyrie
Gradius III (SNES port though)
Hellfire (This one is pretty sweet)
P47 Aces (Batsgun syndrome. A+ game ruined by a silly scoring trick)
Strahl
So yeah, not a single R-Type game on there

It seems that most (if not all) of the non bullet hell horis I have played have had either no scoring, or scoring that I did not enjoy.
Edit: Oh yeah, I played Dux to level 3, which was utterly painful. It probably doesn't help that I enjoyed Last Hope so much, since Dux almost feels like a spiritual sister to Last Hope... well, at least until you start playing it.
