I've grown them both. (Funny how I started this topic.) They taste different. Orange Jazz has one of the more unique flavors among orange tomatoes, in my experience, and it's the same color of orange as Amana Orange (sans the stripes). Amana Orange is a relative to it, and it shares some of its flavor. Sweet Ozark Orange is definitely more meaty and peach-like than Orange Jazz. Orange Jazz was more prolific for me. Sweet Ozark Orange had bigger fruit. Orange jazz had fibrous deep veins attached to the calyces.
