Huge and Enormous are synonymous words and can be used as same. It depend what you are trying to say. But most of people would understand what you are trying to say. If you have any questions you can skype me at cesar.kha1. Cesar.

Yes:-) thanks!

I use huge/enormous to describe big things with neutral connotation , and I use great to describe something with positive connotation. I hope this helps
