we are looking to get a new credit card and DH and I are arguing about the best rewards to collect. He thinks cashback (we have one that currently gives us 1.5% on purchases) is better, whereas I think accumulating points for travel is. There are a few cards out at the moment with great introductory offers on points (none that I can find that have introductory offers with excessive cashback) and because we live in the States and to fly home costs so much I'm keen to get on this soon so we're not worrying about the cost of flights for next summer, for example. His point is if the cashback is worth more then we use that to pay for flights, which is fair enough.
NB we do live in America where I think the culture around credit cards is slightly different, everyone uses them here because you literally can't do anything without a good credit score so we would move all our spending to CC to maximise either points/cashback, using YNAB to track all spedning and pay off every month
