Whitebeard had both the younko status , and strongest man.
Hes main fighting style was around his devil fruit power.
You cannot and should not compare whitebeard to shanks.
Shanks is a swordsman, does not own a devil fruit, and doesnt hold any title besides being a one of the younko.
You shouldnt be annoyed by the fact that till now all evidence shows that mihawk is stronger then shanks if they were to go 1 vs 1 (no crew/allies involved)
Unlike whitebeard was, mihawk is currently at his prime.
Take a look at this

Due his health getting worser and worser, it could be up to debate if WB was still the strongest man in the world, at the time of the marineford battle.
Even crocodile says WB is ''weak'' compared to what he was not that long before, imagen what a true monster WB would have been when he wasnt sick and dying.
Blackbeard mentions it aswell

Secondly, i think its fair to assume that everyone knows that Mihawk excels in swordsmanship compared to shanks (swordmanship includes haki)
Yet people still bring up this ''overall fighting skill'' or ''all out'' whatever you want to call it.
However you fail to answer, where lies the difference in swordmanship (including the haki) and ''going all out/overal fighting skill''
Isnt that the same thing, since shanks is a swordsman.
If you do not think its the same thing, then please provide evidence of this so called 'overall fighting skill'' or ''all out'' that shanks can do.
Besides, like luffy, i think shanks has this ability too.

The ability to turn those around him, into his allies, the most dangerous ability of all
PS: im not a troll just because i think this way
Mihawk = strongest swordsman not questionable.
Shanks = swordsman
Logic tells me mihawk > shanks.
