Which one is better, Kacolor filter set or Meiko filter set?

I bought a filter from Kasejia. When I got it, the filter box was covered with dust. I couldn't help but doubt the quality of the product. I have been buying filters from Meiko since then, and I am very satisfied with them from single filters to filter sets. In my daily photography, I find that when shooting in strong light or chaotic light environments, the camera cannot take advantage of the large aperture, so I I bought a three-piece set of scenery. I installed it and took some photos. It is indeed powerful. The photographic effect has been improved a lot. I can finally decide the aperture under strong light. I will consider getting an ND1000 later to shoot streamers and play with the slow shutter effect. The filters are much better than expected. When you go out to shoot, just use the filter bag that comes with the set and take it with you. It is very convenient.
