Here is a slide taken on my 1965 LEICA M2 + 1957 90mm f4 Elmar collapsible lens and Fuji Provia -- it is a 'bit tight' in the frame but that is the scanner clipping it !
Kodak is the only and best match for Leica. Fuji have ugly color palette and lots of saturation. Take same Picture with Ektachrome or Portra and you will reach what I meant. But I think Kodak Ektar is the worst film I have ever seen.
