Summer Breeze is a Mosti Mondiale product, while Orchard Breezin' is an RJ Spagnols product. Both should make a sweet low alcohol wine. I would imagine that the results are quite comparable but have never made a Summer Breeze kit.
Pick a flavour that you like (not the grape variety) and make it. For example, I like the OB Blackberry Merlot, although it is too sweet for us diabetics, the flavour is great. And it makes a wonderful wine jelly. For comparison to this one try the Wild Vines Blackberry Merlot.
Vineco's Niagara Mist Sangria Zin Blush is the current family favourite. Gotta get another one of these started.
