One Piece Episode 445

[Kraco]

He seems like he would be around Mihawk in skill, at least.

I very much doubt we have seen even the tip of Mihawk's skills. Although the same goes for Shiryu, but it also means there could or couldn't be a big gap, either way. One thing is clear, though: Shiryu does have self-control issues and that's rarely a good thing in a swordsman.

[Assertn]

Yeah, mihawk seems far more tempered (no pun intended) with his self control.

I say Shiryu is at least close to Mihawk, because Magellen feels that he alone is enough to take down Blackbeard, and they (Blackbeard and Mihawk) are both Shichibukai. Magellen also thinks he alone is enough to take on Luffy, Crocodile, and Jimbei. Which is a group made up of someone who has beaten two Shichibukai, a current one, and a former one. And apparently Magellen and Shiryu are equal. I guess I'm also treading dangerously close to power level arguments (which I'd want to avoid), but I'm just trying to say that Shiryu is probably a world-class swordsmen, which would make him really powerful.
