This is a great compilation from a great band, and right from opening tracks "Fool For Your Loving" and "Don't Break My Heart Again" establishes itself as lively and upbeat, only slowing down toward the end for "Ain't No Love" and "Too Many Tears" (even during which it maintains a strong groove) before picking up again. The recordings are clear and not mangled with "remastering". The only real problem is that one CD just isn't enough to get everything good Whitesnake did, so I suggest also looking at The Silver Anniversary Collection (2CD). There is some overlap, but neither is a subset of the other (nor does the three-CD 30th Anniversary Collection cover everything on these!).
But if you're uncertain, this is an excellent selection of hard rock at a ridiculously low price, with MP3s available to preview. It's probably also the "densest" collection of good tracks, if you need something to play in a car stereo or such. Go for it.
