I'm fine with either. The big advantage of the old way is if you have something approximately the right voltage (and sufficient wattage) all you need is a $0.2

I'm fine with either. The big advantage of the old way is if you have something approximately the right voltage (and sufficient wattage) all you need is a $0.25 barrel connector to charge. I damaged the power brick for my laptop once and ran it off of a bench supply with the original DC cable while I was waiting for the replacement to arrive in the mail. With USB-C PD, If you live sufficiently close to a Best Buy (or similar) you can usually just get the USB PD brick with the most listed versions supported and have it work "good enough" but I have definitely seen laptops/PD brick combinations that negotiate rather low power.
