Simply a matter of personnal taste and pardon my bias... I always love hearing Dennis' grooves... He makes it sound soooo Dennis... Yep, I'd agree, the ghost notes are louder than on Rosanna's. But again, it sounded... Dennis. As he himself said, t'was his own interpretation.
Where did Jeff Porcaro get his Rosanna groove from?? Wasn't it inspired from a John Bonham groove as well as from a Bernard Purdie? He took from them and made his own. I see nothing wrong in Dennis taking from Jeff and doing his thing with it, again, just a matter of what one likes and dislikes. As far as Dennis' solos, his solos have never been my favorites to listen to.
