Ohhhhh shit this one actually looks good.
Okay, let's get here:
For Link's side, he has resistance to almost all of Thor's powers, including: electricity, fire, trasmutation, power null, illusions, heat, magic, BFR, energy etc. Plus being able to negate his regen, void manipulation, one hit kill, existace erasure, and a shitton of things that I'm too lazy to mention.
On Thor's favor, he has a couple of resistances to Link's hax like time, matter, soul hax. He can also one shot Link through the AP, as Marvel's 4Bs are 300+ KiloFoes while Link seems to scale the Triforce which seems to be baseline.
There are many factors here to take so I will go with Inconclusive for now, until more imput is given.
