Very interesting, especially regarding the filter system that don't vignette.
I noticed that neither Cokin nor Lee filters were part of the evaluation.
Personally I have owned and used Cokin, Haida and Nisi, so far, my conclusions are:
Cokin:
As beginner I originally owner some Cokin creative kit, but it was very cheap (no glass), not even worth selling it used. I upgraded to Cokin Z pro with Nuance and Nuance extreme glass, and that glass is top notch, better than Lee filter glass, the best I've ever used (fully neutral, no fringing, sharp), but Z pro filter older is
very cheap and vignette.
Haida:
Haida filter holders in principle should work, it's very thin, but practically not easy to use, threaded aluminium frame too thin. Haida 150mm glass is OK, quite neutral, but coating isn't great, fringes on wide angle against strong light.
Nisi:
I use the V5 / 150mm filter holder, works great to easily insert/remove filters plates, thanks to lateral springs force, unlike most other filter holders that pinch glass edges
Now, I've just seen that Cokin offer a new and magnetic filter holder + frames that can (apparently) take Nuance glass filters. Eventually I can upgrade my filter holder for not too much money and keep using Cokin Pro glass filters.

A few years back , Lee filters were quite popular, but have strong color cast (big stopper), which, by today standards isn't good anymore. Especially with 10 stops filter, correcting color cast requires an extra time consuming step of long exposure with a white balance card.
