>I just got back from Japan. I did not notice a difference in performance between tapping with a Blink credit card and tapping with an IC card. I only used the ICOCA card.

Unless things have changed, the ICOCA uses Felica as well. And old Offline Credit Card transactions used to be 200-300ms. Compared to Felica that is sub 100ms. May be offline transactions for credit card have gotten faster? Or may be not latency sensitive enough to notice the lag.
