Reversal printing has certainly suffered with improvements in digital, but I think the thing that really killed it off had to do with new shipping restrictions that made it difficult to acquire the chemistry, particularly if you wanted to do R-3000 in small batches.

I liked the look of Fuji Type-35, which had good color (I preferred it to Kodak Type-R) and less contrast than Ilfochrome, but just as I discovered it for myself, the chemistry disappeared from the market.
