While there is some overlap in Epic and Honour - the geranium, and general spicy/woodiness - I don't think they're redundant. Honour is a bit more refined, Epic is earthier. I tend to think in colors and hues when I smell scents, and Epic is a lot of earth tones of natural greens and beiges while Honour is more white (the tonka), light green, and yellows, with a bit more shading to it, too (the patchouli in the drydown).
Honour would make for a great daily or signature scent imo. It's not overbearing, and seems like it would function well in almost all situations. I find Epic to be more of an occasional wear. While I know a lot of guys like and wear Epic regularly, I only really feel compelled to wear it when I'm going to be outside for much of the day. Odd as it sounds, it's the perfect scent for something like a renaissance faire.
