Just more of a datapoint then anything else. As you said cobranded CCs have been around for many years with many different banks and institutions backing them. Sometimes it's more obvious then others. And some people although they might be interested in a particular card will not want to deal with a particular bank / financial institution for some reason.
OT a bit but I noticed an interesting thing. The extra cash back % is based on the code that is attached to the venue. It's part of the information transmitted to the CC company so they know they you are in a restaurant or home improvement store or whatever. If you read the fine print that comes with card documentation it's stated that if whatever establishment does not send the proper code you may get less cash back because the restaurant may not be sending as a restaurant but a "gourmet food store" or some such thing.
THIS card is a bit more liberal in what they give the restaurant cash back on giving the higher cash back on some places that other cards (Discover / CiTi / Cap1) DO not classify as restaurants. Is Ralph's Italian Ices really a restaurant is a discussion for another thread but I did find it interesting that Gemini / WebBank thinks it is but the other above 3 do not. And since it's still so hot out I will be verifying this a few more times over the coming days to make sure it does not change :-)
Although I do think the metal card is cool I have now found there are some places that the card slide on the CC machine too thin for it to fit. Would have thought that something like that was an industry standard.
