Honestly it was just lack of injuries and bad panelling and that made a lot of these fights underwhelming. The Robin Fight is the best one since it implemented some of those elements. Black Maria also, unlike the other tobi roppo, had a counter for a lot of what was thrown at her. Robins fight is the only fight so far somewhat remincent of what oda did with pre timeskip Strawhat fights.
In the end I think Zoro, Sanji and Robin will have the best non luffy fights in the arc.
