Any opinions on vinyl gutters vs. aluminum?

In case it matters, this is for Central Florida, where the sun is fairly intense
and in the summer we're prone to many thunderstorms with large volumes of rain
(generally short periods of heavy rain vs. extended periods of lighter rain).

I'm looking to put these gutters only in certain areas of the house where rain
is causing problems.

Price is not really a factor. Vinyl is a little cheaper but not enough to make
a difference if aluminum is really better.
