I am definitely going to cancel and switch to the Chase card. I had this card because it was my Priority Pass access, I like the Marriott credit, and for the ENC. I'd rather switch to the much lower fee Chase for the ENC and get a different card with Priority Pass. AmEx Priority Pass isn't as good as Chase/Capital One anyway!
Unfortunately, I'm still 6 months out from my two year bonus anniversary for the AmEx. Here's to hoping that Chase has another generous offer around then!
