Well, I like mine quite a lot. It's quiet when I want it to be quiet, and it's loud when I want it to be loud. It never pops, sounds smooth, and has a nice low timbre. In terms of appearance, it's actually a little showy for my tastes, but I let the cans stay dirty, and generally the tips too, as long as they're not unsightly. I would rather the tips be a little bit smaller and rolled, but hey, no way am I changing them now. The sound is exactly what I want.
As far as the N1s...well, for starters, I think they look ridiculous. Those tips remind me of pierced ears with huge-gauge things in them. Or a saggy ass, whatever you prefer. Maybe you like them, but they're not to my taste. I just feel like the legacy is more of a darkhorse/sleeper vehicle than your average modified wrx and a way to have just as much go with a lot less show (i.e. unwanted attention). I've never heard them, so I can't state any sort of legitimate opinion on how good or bad they sound.
just my .02
