I’ve had both and if you don’t carry much, the B25 noir ghw is more desireable I think. I’ve carried both filled up to the brim and the B30 isn’t that heavy, (b35 is heavy) and B25 can suprisingly carry alot. But.... it’s the handle drop that turned me off from the b25. I like to be able to carry my bag up to the crook of my arm and not just handheld. I have big wrists so the b25’s handles can’t go up further than that. That was an expensive mistake made, and even though I love the look of a b25 I had to rehome it.
