He is one of the few characters that try to improve their abilities, unlike others (Buggy for example). So I wouldn't be surprised if he is around the strength of a powerful Shichibukai now.

Smoker's and Luffy's relationship is very close to what Garp and Roger had, so I guess he will be still ahead of Luffy after the time-skip, at least being able to still give him huge trouble.
