Do a search and you will find a ton of info on Gunzilla. It's the best on the market IMHO.
That I can't tell you as I have never used Eezox, I'm sure someone here has tried both though. Good luckI've done a couple of searches. If you Google Eezox you will see alot of great responses on that as well. My question is which is better based on hands on experience with both products.
