Well, I've seen both already myself. F91 is 'okay' it's pretty apparent how 'crunched' it is to fit, what I recall was a first arc, into just two hours and seeing as I can never get him to read manga anyway (where as I understand it the F91 story 'sort of' continues?) it feels a bit pointless.
Also, I mean, maybe this is a controversial opinion on here, but I really don't like Victory Gundam. Over the last year I struggled through it and generally think it stands as one of the worst entries into the franchise I've seen (I have not seen: Gundam X, Turn A, Seed Destiny, MS Igloo, Gundam 00, Builders, Age, Build Fighters, or all of Thunderbolt), excluding Reco in G which I made my wife suffer through and she still hates me for saying "Don't worry, it'll get better!"
I am open though to people convincing me that he should see them however. Maybe I just didn't "get" why they were good.
