I have both of the Republic serials on laserdisc.
I also have The Assassination of Jesse James by the Coward Robert Ford on HD-DVD, The Days of Jesse James (Roy Rogers) on DVD, The Long Riders on Blu-ray, and The True Story of Jesse James on DVD.
I watched it over the weekend and found it to be very enjoyable. The Technicolor is unavoidably compromised, but it didn't detract from my viewing experience and it is a significant upgrade over the 2007 DVD. The film takes many liberties with the real story of Jesse James, but who cares?
