Best credit card for use in USA

[Zippee]

Hi all, I'm heading to the US for 2 weeks in July and prefer to put the majority of transactions on c/card rather than cash. I have an Amex platinum and RBS master but they both charge for non sterling transactions. Any tips on the best cards for USD? I pay off in full each month so not fussed about other special offers on them.

I've kept my nationwide credit card for exactly this reason.

For every sterling transaction completed you earn commission free FX transactions.

Thanks all. Especially above, forgot about N/wide who I have a flexaccount with and they offer a cashback card with zero commission.
