In colour, Kodachrome excepted, nearly all my colour work is with Fujichrome — usually Provia 100F, 400X, T64, MS100/1000 cold-stored, etc. I did try out Ektachrome E200 and it wasn't bad, but the colour palette will take some getting used to if I return to it again. I do like the Ektachrome tungsten (320T, 160T, 64T) look a lot. Presently, I'm shooting nothing but Kodachrome in my 35mm cameras. In b/w, I just avoid Kodak and use mostly Ilford HP5+ (sometimes Delta 3200P) and used to use Agfa APX emulsions, though recently have begun trying out Efke and soon, Rollei emulsions. I have never shot Fuji in b/w. I don't shoot colour negatives, but I have a ton of frozen 220 rolls of NPS160 (I think) that came with an MS100/1000 120 and Provia 220 lot. I've never shot it, and I have doubts as to whether I ever will. I'm guessing they'll languish in perpetuity.
I went with "more Fuji than Kodak", but that's a simplified reflection of my experiences.
