If Mihawk really is stronger than Shanks, in the chapter where Mihawk bounty is revealed, why not say “Dracule Mihawk is better than Shanks.” Why bother specifically saying “Mihawk has better sword skills”, I mean isn’t that obvious? Everyone knows he’s the greatest swordsman… This shows Oda wanted to make sure people knew Shanks > Mihawk, otherwise he would’ve just stopped at Mihawk is even a greater fighter than Shanks.
