The Master Sword isn’t really a strong sword, it’s more just an extremely anti-evil Sword. There have been equally strong or stronger swords in Zelda canon than it. I don’t think it gives him any advantage against characters who are not objectively evil lol.
Yep, it's a bit difficult scaling the MS based on its ability BUT! The sword itself was forged by the power of the three goddesses. Hylia used the Goddess Sword to fight off Demise. This is the weaker version of the Master Sword.
I don't know a single sword which is stronger than the MS canonically. Sure, there are stronger weapons gameplay-wise but within the lore, the MS is the nr. 1 sword.
Link was basically worthy of wielding said sword - that already puts him very high. Ie, The Wind Waker Link had to make special trials - made by the gods - in order to be worthy of the Master Sword.
Powerscaling wise, Link is already stronger than the likes of Onox and Veran - Ganon's Commanders in the Downfall timeline - who are stronger than some weaker deities. But these deities possess abilities which would be already dangerous for the mankind for example.
Generally, the Zelda verse itself is so much stronger than the OP verse. OP top tiers wouldn't be that much high in Zelda powerscaling. So unless logia users can save themselves with their elemental intangibility, Link usually wins every battle against them. Nevertheless, I get where you are coming from. OP is generally a verse with good destruction stuff in which a video game verse like Zelda wouldn't look more impressive at first but in these cases, the lore of said verse can decide so many things.
