The real difference is in the game system, as that pretty much affects everything else. While S&S1e used a system that was unique to it, S&S2e uses a system based on Labyrinth Lord/BECMI. Character generation is roll characteristics on 3d6 each, choose race, choose service branch (or class). The number of races has been increased, though. Advancement is still level-based with increasing levels bringing increased skills and equipment allowance.
The fluff text is still intact, and the background is the same.
Personally, as an owner of both, I think S&S2e is worth it; and the game has received some good feedback whenever I have dragged it out at conventions.
