In my experience, in IT, cables are usually the way to go over adapters. Adapters tend to break more often than cables.

Someone else may offer a more thorough differing opinion… like perhaps a very high quality HDMI cable with a high quality adapter may be better than a mediocre off-brand standalone cable, but if the prices/brand are the same… I’d stick with the single cable.

Before USB-C became standard, we stuck with HDMI cables and then had different adapters on hand just for convenience, but if we knew a cable is going to be used in the same equipment for a long time, we’ll try for the single cable.
