Michael Bourgon sets ANSI_PADDING:

We know that SQL Server can cache multiple query plans for the same query based on the SET_OPTIONS for that query, and that SSMS doesn’t have the same options as the standard library. (https://www.sommarskog.se/query-plan-mysteries.html). He even includes a chart!

My initial comment was “Michael Bourgon sets XACT_ABORT” but that’s actually not one of the list, so I had to change it for the sake of correctness even though I think it was funnier in its original guise.
