I just returned from a week in Italy. According to online accounts:

CapitolOne GoCash card - charged approximately published foreign exchange rates. Not sure if I'll also get 1% cash back or if it's already taken into account.

Citibank ATM - about the same as CapitolOne.

Chase ATM - much worse. While CO and Citi were charging ~1.26 $/euro, Chase charged ~1.31 and added a $3 service fee.
