Elves were genuinely stronger than Dwarves and Men

I see little reason to see why Glorfindel or Ecthelion are far superior combatants than Beleg.

So? So too were a few of the Sons of Feanor yet Fingolfin is surely above them.

Third Age Glorfindel scares the Nine.

Glorfindel >>> Beleg.

Not really, I kid. Turin likely surpassed Beleg, but if they fought earnestly, it would be very close I would imagine. Beleg is no pushover.

I wouldn't even say that Turin surpassed Beleg in skills maybe in strength.
