i like damier, epi, and monogram mat. i dislike monogram canvas, i think b/c it is SO "everywhere." altho I must admit I really like the Ellipse PM in monogram. I would make an exception for that one I think b/c it's such a unique shape . . .
Although I have a mono Speedy I really prefer the epi line and suhali line. I have to two bags from the epi line and one bag from the suhali line. I probably won't buy anything else from the mono line.
I like mono, damier, epi and denim. However, I lean more towards the damier because it's classy and yet understated. Mono speedy 25 is probably the only mono bag I'll ever get (next to my mono mini HL). I just don't like flashy bags.
