If you like it for your current use, you're fine.
If you're just curious as to whether or not there are superior parts or worked out packages, then yes there are (in a wide range of price points). The thread Sleep referenced is a good start.
If you're wondering where Ford's Handling Pack sits within the pecking order of the mentioned range of packages, then you'll likely get a few opinions on the matter. Obviously they're better than stock, as you've witnessed. Can you do better with similar money, I think definitely so but not so much better that you should think you have a horrible package. When it comes time to upgrade, you have room to grow. But first, grow your skills with the car you have now.
Best,
