Her chase is not the same, sailor sakura owns a repulse to highfloat chase, and remember that the whole point of sailor sakura is her attack that hits 4 targets, thing gnw sakura don't do. Yes, potentially gnw sakura can heal even more than sailor, but who delivers the damage in that team without sailor sakura?

About the request of the OP: han wtih azure fang without sailor sakura works or with a triple healing team, but not in arena, or with a double healing + one shielding ninja, like gakido or kurenai, but also this one not in arena and in both the cases we are talking about teams for round 10 endurance (in no way meta teams, i want to be clear). Otherwise han works better with scarlet blaze and full cc teams.

About roshi he works well or with stacking shield ninjas with crimson fist or, by running azure fang, with teams that let you for sure use his chase. Ninjas like Yagura/Utakata/Yugito nii are mandatory to let you do so (for example a team i tried for fun is yugito nii, roshi, bee sst/fu that actually in arena are giving out better outcomes than i thought they could do, but outside arena are pretty squishy due to the weakness of yugito nii or yagura, or also sage naruto, roshi, yagura works nicely.
