In my opinion it depends on how confident you feel in your algebra ability. Pre-Calculus is likely to be the more advanced version of College Algerbra, so if you feel confident then I would go with pre-calc.
Remember that mathematics is always building on previous concepts, so the new material will make a lot more sense if you have a solid understanding of the old material.
Another thing to consider is whether or not you plan on eventually taking Calculus. If so, you might want to do Pre-Calc. That said, both would be useful, so it's really a matter of how confident you feel and how much you want to be challenged.
Hope this helps!
