  I can only think of NYC as having a better payment system as they were
  first movers on tap-to-pay adoption and it's basically fully adopted.

Portland's TriMet had tap-to-pay well before New York.

  I was in Paris in the last year and I don't think public transit
  payment was better.

The multi-stage turnstiles at the RER stations… ugh.
