Vegas is an awesome tool. I had used Premiere and just hated the interface (a personal opinion). I found Vegas to be really intuitive, and with its compositing tools I rarely use After Effects now.
Also there is really no tool out there that has the audio capabilities of Vegas that are built-in. Lots of audio plugins, plus native 5.1 support, and it is really easy to mix your 5.1 tracks.
Coupled with Vegas DVD Architect it does everything I want, commentary tracks, motion menus, etc.

You will see very little complaining about the product, unlike in ther NLE forums.
