The way I see the WoL, and it's something that generally carries looking at other evidence, is that at the point of Shadowbringers and Endwalker they're at the top of their particular style of combat (whatever that is), but not to a degree where it's beyond what your regular person can do. In superhero comparisons, we're not Superman, but we're probably Green Arrow.

That doesn't mean the WoL doesn't have to try--just because you can kick a tiger's ass doesn't mean you can let your guard down--and it doesn't mean they don't have equals when it comes to one-on-one combat; remember that just in ShB and EW we've had fights considered near-equal 1v1s with Ran'jit, Zenos, and multiple Bozjan duels, all of which were depicted as 'normal humans at the top of their specific game' (as long as we excuse the Gabriel and Hypertuned Dabog from the duels, who are their own thing). We fudge the numbers on what's considered 'normal human', we can also factor in fights like Elidibus in both Zenos' and Ardbert's bodies where it's not really clear what extra Elidibus is bringing to the table, but also that he's not exactly breaking many rules of what we'd consider possible anyway.

But, as Dikatis said above me and I want to really underline, the WoL has the greatest strength of all larger fights: Remembering that it doesn't have to be 1v1. To a degree it's almost not important how strong the WoL is solo, because using that as your only metric for their strength or chances of success would be like estimating the success of an entire football team solely on a single player.
