No experience with with now-gone Ilford, but I've made close to 1000 prints on the Canson Baryta from HP Z3200, Epson 4900 and Epson 9900 machines, since the Canson Baryta was introduced several years ago. While I do have custom ICC profiles for each of these printers, the canned Canson profiles were all pretty good. The Canson is a very nice paper and a decent dollar value. It does contain OBA compounds, as you'll be able to read here, but the prints I've had on display for a few years, in naturally lit environments, look fine (for what little that's worth). The Canson Baryta is my go-to paper for the "fine art poster" projects I do, all of which receive a laminate after Gator foam mounting. They look quite nice, honestly. But the Canson prints also look just fine under Museum glass with traditional framing also of course.
