Hello.
In my humble opinion, the design of the database should not depend
on operators which you're going to use in your queries. Yes, using
INTs in the IN clause (that means the the column type is INT as well,
isn't it?) should be a bit faster, because operations with strings are in
general
slower than with numbers.

When using IN should i design the database to use int's or is the performance
equal?
WHERE col IN('test','test2','test3')
vs
WHERE col IN(1,2,3)
