in YOUR opinion, which is better for fountain pens, Kokuyo Shikkari / Sarasara, or the paper MUJI uses for their “flat-open’ / “looseleaf notebook” notebooks?

In my opinion, the paper they use their open flat notebooks or the looseleaf ones are soo smooth and can handle ink better, on the other hand, Sarasara for me is the minimum. It’s good untill you get hand oils on it and whenever i swatch ink on it using q tips it looks ugly, compared to when I swatch with q tips on MUJI’s paper, I’ve also never tried Sarasara so give me your opinions
