Nope Marco doesnot,yet he has decent feats against the top tiers he faced.
Luffy on the other hand? Fs didn't save him from being oneshotted by Kaido or running away from Big mom recently.
Until Luffy has even one even clash with any of them,Marco is stronger in my book.
He didn't use FS due to PIS, I mentioned this as a caveat. I am talking Luffy's proper fighting potential not him when he is written to extend arcs due to PIS. He has subsequently trained his FS further.
In any case Raimei Hakke is a knockout technique, an inferior version from Yamato oneshot Ulti, and unnamed version oneshot Oden. There is no shame in getting knocked out by it when you are bloodlusted and not properly defending or evading.
He wanted to save stamina for Kaido.
Luffy didn't have basic ryuo in his Kaido battle and so was unable to damage Kaido, now he has the level beyond.
Marco got restrained by Big Mom very easily, and trashed by an unnamed Garp fist, hardly feats to put him above Luffy.
