Aluminum gutters are better than vinyl gutters because they don't rust, and they're also more durable.
There isn't a definitive answer to this question since both aluminum and vinyl gutters have their pros and cons. Aluminum gutters are often considered more durable and less likely to rot, but they can be dented or scratched. Vinyl gutters are less likely to dent or scratch, but they can warp in extreme weather conditions. Ultimately, the best gutter type for your home will depend on your specific needs and preferences.
