Garbage? What makes you think that?
Because the interface was murdered by HTC with the addition of Sense. I have despised the Sense UI ever since I owned the Eris. The Eris was a piece of crap, this phone will be a piece of crap with a better processor. Big deal.
To be fair the device itself is very competent, it's just that some people, like yourself don't like the Sense UI. I would argue that this is fine and you should just disable it like all the other Sense UI devices and go stock Android. Unfortunately you cannot disable Sense on the Incredible.
As for the N1 over Incredible the only reason I would choose the N1 is the fact that it gets its' updates directly from Google. No waiting for 2.2 or 2.x to be rebaked prior to distribution whether OTA or via local download/PC. So in that sense yes the N1 is superior to the Incredible.
