For most drops on most maps, it doesn't appear to make any difference. Some require S-rank clears to drop. Isokaze so far appears to only dros on Medium & Hard E5 boss, S-rank only. Wikiwiki's drop lists also suggest that Harusame in E3 is Medium & Hard only, Yahagi may be hard-only in E4 and I-401 also Medium & Hard only for E4. May want to consult other sources on that if any of those drops are of interest to you (I've already got them all personally aside from Isokaze so haven't researched further).
