I'm not sure how Chase is in the US other than probably more popular but their fairly recent launch in the UK has been great. I like the cashback and for better or for worse luckily max it out most months.

I think the only reason I haven't moved everything into Chase is hassle of moving everything and there is a slight sentimental feeling towards my Barclays account as it was the first account I had since I moved to the UK many years ago.

it's a dumb reason to cling onto the Barclays account but it is what it is.
