Single target NP is the only reason I'd ever choose Medb over Summer Mordred. Medea Lily is good for raid events (I like Irisviel more, though), but I wouldn't use her for much else.

Of course, if those two specifically are high-priority on your want list, then this gacha is your best opportunity to get them. I personally never use the Story Summoning gacha, because it's just not reliable if you're looking for specific Servants. I'd wait for Rate-Up Summonings to maximize my chances.
