Well, I'd say it's great for everything except top speed. It's not a fast ship. But you'll find it's high thrust and handling gets it out of corners faster, which more than makes up for this. At Phantom class, I think the top speed is far less important than it is at Venom class, so AG-S really is a great ship (although it's too "twitchy" for me).

btw - EG-X is the best!
