The Death of Superman is one of the best arcs ever overall, I'd suggest picking up the whole batch(or the TPB if you prefer).
The core "Infinity" series(Gauntlet, War, and Crusade) are all good, but there is a slight drop in overall with each progressive arc.
Crisis On Infinite Earth's is good if you're good at keeping up with a complex storyline(it can be pretty confusing at times).
Almost anything from Spiderman in the 90's that doesn't feature a clone is worth reading.
