Yes Harman FA AL is very shiny, the closest to ferro-typed, but so much so that it is not ideal for inkjet printers. Harman has a lot , really a heavy hand of OBA as the paper backing is not that good of a base. Although I like Harman for it's look, the splendor wears off overtime and looks a bit too much, too shiny, too plastic like, and way too brightened.
I don't like the Hahnemuhle FA Baryta surface as it has too much eggshell dimples. PR Baryta though is the right combination of everything , shiny but not too much, cotton rag but very bright, no OBA, yet still white and neutral, lies flat but still has a paper feel, etc.
Epson Tradition is nice enough, I have yet to try the new HP Baryta, but for a premium non OEM paper that is or should be at the level of a ( European Epson certifiable print standard) media PR B is already one of the best in this league. Digigraphie
