I use Revolut when I’m abroad or buying something in another currency as it’s cheaper than using my banks (a UK one) or PayPal’s conversion rate. For day to day banking though i still have my traditional bank account for day to day stuff. Their free tier is fine, they do suggest you upgrade but the benefits just don’t save me anything personally. Sounds like the US market might actually be more competitive though? Just to add we don’t usually pay for current account here in the U.K. either although there are some around.
