How efficient is Filtering a database search using "Created By"?

Hello everyone. In my app I have a number of “Products” attributed to each “User”.
Currently, each product contains the name of the User who created it. When I do a search, I set the constraint “Name = Current User’s Name”.

However, another option is to simply do “Created By = Current User”.
My question is: Which of the two options do you think would be faster? Has bubble optimized the “Created By” option to be faster? Please assume that no two users can have the same name in my app, so duplicates are not an issue.

Much appreciated !
