Burn all the USBC cables with fire except PD. The top PD cable does everything the lower cable does.

    IDK I’ve had PD cables that looked good for a while but turns out their data rate was basically USB2. It seems no matter what rule of thumb I try there are always weird caveats.

    No, I’m not bitter, why would you ask that?

    There are many PD cables that are bad for doing data.

    Correct. The other commenter is giving bad advice.

    Both power delivery and bandwidth are backwards compatible, but they are independent specifications on USB-C cables. You can even get PD capable USB-C cables that don’t transmit data at all.

    Also, that’s not true for Thunderbolt cables. Each of the 5 versions have specific data and power delivery minimum and maximum specifications.

    I don't think this is right. The PD standard requires the negotiation of which side is the source and which is the sink, and the voltage/amperage, over those data links. So it has to at least support the bare minimum data transmission in order for PD to work.

    Technically, yes, data must transmit to negotiate, but it doesn’t require high throughput. So you’ll get USB 2.0 transfer speeds (480 Mb/s) with most “charging only” USB-C cables. That’s only really useful for a keyboard or mouse these days.

    You forgot thunderbolt and usb4 exists now

    True but pretty much the only devices that need those are high-end SSDs and laptop docks and in both cases you just leave the cable with the device rather than pulling it out of your generic cables drawer.
