The more you travel the more you encounter hotel rooms with distant sockets like behind a bed and so a cord works most flexibily. Or airports where there is 1 socket already in use so you can share it with an extension cord.
I spent 7 weeks in 24 different sleeping locations last summer. The issue is not so much the socket type but the socket location and its reliability. Plug-in non-corded chargers are great in modern, knowlingly good quality+location situations.
