More than just bricks fitting into each other at a superficial level, it matters how firmly they fit together, and it's one of the areas where LEGO is generally superior to the similar types of bricks.
A detail I didn't realise until I was an adult was the difference between the black and grey technic connecting pins. They look interchangeable, and for a lot of things they are.
But there's a fraction of a mm raised lines on the black one, and it's enough to produce significantly more friction, and that difference is utilised in designs.
And apprently there's now a new version of the black one, and people notice these things, and measure them - this article gives an idea of just how these tiny changes, well below tolerances for some of the "knockoffs", can produce a different effect:

Do you mean between black and light grey? Light grey pins have always been the kind you use for rotating connections (low friction), whereas black was for non-rotating ones (high friction). Newer blue pins are also high friction, IIRC. I haven't bought new lego technic in a while, so I don't know if there's been any new colours added
EDIT: I think I also had some dark grey pins, but I don't remember if they were high or low friction
My memory of twenty years ago says the dark-grey pins were 1 stud wide on one side, and half-wide on the other, and low-friction like the light-grey ones.
I think they were light grey as well. They were commonly used to make cranks out of the 4185 belt wheel or attach objects to the wheel.
> Light grey pins have always been...
I think the black ones were a later addition, likely late nineties.
Per the article I linked to, '93.
Which is presumably why I didn't notice until my son started playing with it, as I'd stopped playing with mine by then.

Imho, this is, objectively, not true (anymore).
Pantasy with GoBricks are superior in coloring and fit; Cobi are excellent for things that should not be taken apart anymore (like tank models); Lumibricks are excellent in fit and have amazing illumination solutions that are lightyears (haha) ahead of lego.
I got the Pantasy Neo Geo set a while ago, and was pretty blown away compared to the better known imitators that have been available at retail. The mechanics are not as robust as I’d expect from Lego, but it was about a quarter of the price and externally looks as good with some really fun and well thought out details.
Interesting - never come across Pantasy/GoBricks, or Lumibricks but then it's a few years since my son decided he was too old for LEGO, and I see Pantasy is just a few years old, and Funwhole/Lumibricks just a few more. Great if there are more options of similar quality.
But "should not be taken apart anymore" fits into an entirely different category for me. If you don't need to be able to take them apart any more, it fundamentally changes requirements.
True. But lego has stood the test of time. Thats way harder
Lot of time left, by my count
What do you mean by that?

Ha, I noticed this too! And even my 3 y/o picked up on this.
We have a set (something with Spiderman IIRC) that attached wheels with yellow pins that allow for better rolling of wheels. The black pins are too tight for this indeed.
IIRC there's also light yellow pins that are also light friction
