Best way to see if value from one table exist in another

[Pbiuserr]

Hello,
as the title says - I am looking for most effective way to see if ID from one table is in another table in the column ID. I know there is INTERSECT but maybe there are better approaches, faster. My measure get clogged when I reference to this particular one later on

INTERSECT is the fastest.  You can try TREATAS but that will be slower.
