I, personally, would go for the Premiere Pro + After Effects purchase, mainly because I've used both (mostly AE) and they're amazing programs. However, it really all depends on what you'll be doing with them. If you're not going to be doing really complicated animations and insane video editing, then the PP + AE purchase isn't for you, get Vegas instead. But if you want more than just what the generic high-end video editor has to offer, go for PP + AE. Some of the stuff you can do with After Effects is mind-blowing.
