If you are now running 13.3R9 in then network without customer visible
problems with 2GB, and in future you'll have 4GB, I think you're set.
Just because you upgrade your JunOS does not mean you'll be able to
use more memory. By default you'll still run 32b version of RPD,
unable to use more than 4GB. You can ask it to run 64b RPD manually

Newer is always newer, new features and maybe new bugs. I will put on

able to use more CPU cores, and more, like new, is always better,
