It's Century, or a very close variant, unless I'm dreadfully mistaken.
This probably isn't the kind of answer you're looking for, but I don't think there is an ideal one. Aside from the obvious outlying case of Sonic 3 and Sonic & Knuckles, no two Sonic games have used the same title card style. Each one is suited to its own particular game and conjures up memories of it specifically. I don't think choosing one of the lot to ape, or making a syncretist mashup of them all are good ways to go, even when your project is a retelling of the genesis era (as I believe is your goal).
As someone who has been undertaking a similar project for nigh on a decade now, I don't think I've found the right answer either. My best advice would be to just come up with something completely new, but memorable and vaguely Sonicky. With that at least you're being creative and it's very hard to go wrong.
