That has nothing to do with the technology in the IC card.
In terms of real life use, a Suica card in Apple Wallet is indistinguishable from a physical Suica card. Suica itself isn't that much different from any other prepaid transit card, so I don't get the hype. This is some early 2000s technology.
Personally, I see no difference in speed when paying with either an Oyster card (London), an EZCard (Taiwan), a Suica Card, or any Apple Wallet card in transit mode.
