Visa card reccomendationss

My husband and I both have our own credit card (I have master card and he has a discover) - we would like to get a second one just to have as back up and also get a visa just incase we are somewhere Mastercard or discover isnt taken (aka Costco).

I was thinking Chase to build up the points but open to other reccomendations.

We pay off our credit cards every month.
