Every major feature film from Studio Ghibli ranked from best to worst.

Another thing to add is that even if people consider Nausicaä of the Valley of the Wind to be a Studio Ghibli movie, it wasn't officially made by Studio Ghibli before it's foundation, so it will not be included.

I'm so jealous that I never grew up with these awesome heartwarming movies, you don't even imagine. BTW, I watched the English Dubbed version for every single one (with the exception of Ocean Waves since there is no English Dubbed version of that one), in case of you were curious.
