EC Daily Duo and Agendio

I’ve been using the EC Daily Duo this year and really like it for the most part, but I’m starting to look around to determine what I’m going to use next year. I’ve been fiddling around with the Agendio planners since last year because I love how it can be customized, but have been holding back based on just one thing… paper quality. Has anyone used both of these and could describe the difference in paper?

From what I’ve found, the Agendio paper appears to be a relatively smooth paper (compared to the EC) that is white, but is it heavy and can it handle roller ball gel pens with minimal or no bleed through?
