I find it very difficult to get a usable sound from the Savage plugin, but I really like the Fireball model of the Metal Suite. However, there are two things that prevent me from using it more often: First, the file size (the Amp Room plugin weighs in at a whopping 744 MB and Cubase projects with multiple instances of it take forever to load), second, I'm annoyed by a bug that causes the settings to constantly change drastically without my intervention. It happens to me all the time that after reopening the plugin, all the knobs are suddenly in completely crazy positions.
