For product availability, processing availability, ease of scanning and cost, negatives are to way to go. Kodak Ektar and Portra are my favorite films. Great color rendition with Ektar being more saturated, a neg film that has slide film characteristics. And really easy to scan with no fiddling with color or saturation for the most part.

The last place in Calgary that developed 120 E-6 decided not to replace their broken machine. I see slide processing being a big problem soon!
