My 2 Fortuniana Abe's bloom so much better: bigger flowers, and more of them than my Doc Huey grafted Abe's. They are also more black spot resistant. My Fort grafted Abe's were bought at a FL Nursery in the Jacksonville, FL area that stocks Nelson's Roses, which some are grafted on Fortuniana. I believe they were less than $20 each.
