enum or another table(foreign-key), which is better?

[witwall]

for example, I have 18 brands to manager, I can set brand as enum. but one day, I want to add some brands or set some brands as disable, another table will be better.

if use foreign-key, there will be another issue 147 I met before.
of course I save another unique id, not key column in the product table(who has a column brand).
and enum seems is not a good choice.

Foreign key is better.
