This is not to prove my point obviously, since team for floor 10 is better, but... I don't know, maybe it's just me thinking 10F is much harder than 11F. I don't think there's a point in getting worked up on it, we can safely state that 13F is much harder than 12F, and leave 10->10 as my personal opinion (I hope I am still entitled to it).
I also cleared 11F with full R team (unfortunately without 5 surviving mission, because of dying Oto-hime), but I don't think it proves much either, my 13F team probably wouldn't fare better on 11F (most of later floors require specific teams after all).
