Wire transfers have borderline predatory fees unless you're moving thousands of dollars, and there's still the issue of "oh you entered one of the numbers incorrectly, hopefully they give you your money back!"

I've used Zelle and it was easy. My bank is suggesting them (they have first class support), but I have no idea if they are otherwise better/worse than paypal. Most of the time if I owe money it is either credit card or I used my bank's bill pay (which sends a physical check if they don't have an electronic arrangement)

I did a wire transfer once, $15 in fees, but since the amount was from a house sale (to get from the bank where the money was deposited to my mortgage bank - they couldn't do this direct which was annoying). I wouldn't do it for normal things, but with that much money involved I don't blame the banks for some friction and the cost wasn't much. Hopefully I never do one again, and also I hope I'm an oddity for even doing it at all.
