Fake EC vs renamed EC on a laptop?

Since Catalina, macOS requires an EC device defined in the ACPI tables.

When I first installed Catalina with Clover, I used an ACPI binary patch to rename my Dell laptop's existing ECDV device to EC. Upon switching to OpenCore, I noticed that the guide has instructions on making a new fake EC device, and keeping ECDV active as well.

Are there any practical differences between these two methods? (Note: when using a fake EC, both EC and ECDV show in IORegExplorer - if there are no other differences, it looks like renaming would use slightly less RAM.)
