I think it can be assessed to a degree. For example if it's clicky switch, does it actually clicks at a point of actuation. Is it rated at 10 million presses or 100 million presses. How dust resistant the construction is. Is it easy to maintain/clean. Can it be opened without desoldering. Does the keys wobble. Is operation smooth or bumpy scratchy. And so on...

Well, I tried to at least resolve your first question for Alps and Cherry by googling a bit, but while I have found information for Cherry switches (the actuation point seems to be after the tactile bump/click), I did not find any concise information on Alps switches. Apparently they actuate before the bump/click, but I'm not sure. I'm also not sure what would be better, but if you just want clicking at the point of actuation, your best solution would probably be a solenoid.

If anyone more knowledgeable wants to chime in, please feel welcome to do so.
As for key presses and dust resistance, AFAIK these points would be awarded to Cherry, bu I have no idea about maintenance. Concerning wobble: it seems that at least simplified Alps aren't better than Cherries, but I have no access to any Alps switches, so I also have nothing to add regarding smoothness. From what I've read, Alps seem to be better with this though, at least in comparison to modern MX.
To me (based on other people's experiences, more or less) it seems that Cherry sacrificed ‘better switch feel’ (whatever that means exactly) for robustness. I don't think that makes Cherry switches objectively worse than other switches, though.

Not really, no. At about 8:30 he says that Zealios are more tactile than Browns, but more tactility isn't objectively better than less tactility, just like a louder click isn't better than a less noisy one. Then he says something about the ‘weight’ of Cherry switches, which is an entirely subjective affair.
