Security filter on a table. Which expression is more efficient, or does it matter?

LOOKUP(USEREMAIL(), “Users”, “USER_EMAIL”, "PI_NO”)>=15

My User[PI_NO]>=15
where slice My User only contains the current user’s info based on Row Filter: (USEREMAIL() = [USER_EMAIL])

Of course, this assumes that I wrote the expressions correctly.
