It is a low-level primitive, better indeed to use those operators instead, not call the compare* methods directly. For case-insensitive comparisons you should use e.g. caseInsensitiveLessOrEqual:.
If we want to provide a method that answers -1, 0, and 1 I'd leave the #compare: family alone, and instead add the operator <=> as in Ruby (which would be case-sensitive).
