I won’t rank R1 against the saga films, because it’s basically an EU story; not because of the canon/legends, but because of the purpose the story serves. It’s a very good EU story, I think, but ranking it against the saga would be like ranking the Zahn Thrawn Trilogy against the OT.
I think you can do that. I think of them as just think of them as stories and it makes them easier to compare.
If I had to include everything most of the OT and TFA would not be in the Top 5.
