Hi, which version of the domain has the most incoming links/authority? Also compare top level pages for www vs non www.  I would make my decision on that and then redirect the appropriate one and add a rel=can tag.  If you have pages from the other that are ranking, make sure you are 301ing the individual pages to each page rather than doing a sitewide that just 301s all non www pages to the www homepage (or vice versa).

Hi,

301 redirect is best solution of your question because with 301 you can transfer your all traffic and bcaklinks to your preferred domain. You can check your domain in open site explorer and redirect domain which contain less backlinks. After redirecting you also set a preferred domain in webmaster tool for displaying your domain into SERP. Redesigning of website is really good because it gives Google fresh content of your site you can update content regularly.
