Prominent and outstanding connote a standing out, especially among others of a kind: the most prominent mountain in the range; the century's outstanding figures.
What is salient is so prominent and consequential that it seems to leap out and claim the attention: "Defenders of the pit bull always seem to miss the salient point that it is the ferocity of the bite, not the number of bites, that has made the dog so feared today" (Sports Illustrated).
Remarkable describes what elicits comment because it is unusual or extraordinary: "This story of Mongolian conquests is surely the most remarkable in all history" (H.G. Wells).
Arresting applies to what attracts and holds the attention: one of Ellington's most arresting compositions.
