Okay, go ahead..
It depends on what you mean by better. If you're planning on building an Aerocanard from plans, it's pretty much the same thing as a Cozy. The Aerocanard kits can be viewed at: http://aerocad.com/
The basic kits are the "SB", which stands for "Standard Body" and is the same dimensions as the Cozy Mark IV. The Aerocanard kit is a bit larger than the standard body. Both in kit form can be time savers for anyone interested.
Everyone is different. You'll get out of it, what you put into it. Some folks enjoy the build more than the flying. Others build just to get to the flying. And others just want to fly. You have to ask yourself, "Where do I fall in those categories?" If you enjoy building, like many of us on this and other forums, buy the plans and get started. If you want to build just to get to the flying, go with the Aerocanard kit. It's a little more expensive that way, but you'll reach your goal much faster than with plans built. Or, you can buy someone's unfinished project...and finish it. And lastly, If you fall under the heading of "Just wanting to own and fly a canard", buy one that's finished and flying. There are several out there to buy.
OK!....explain that one. What kind of AIDS?...Hearing AIDS, ROLAIDS....WHAT?
