Neo word drags your attention to engine away from aerodynamics. Neos have Sharklets and LIP Lift Improvement Package that has improved engine strakes and better slat seals improving lift and reducing drag.This when closer to ground makes it difficult to drop the excess speed of GSmini. That's why in Neos the GSmini uses only 33% of difference in experienced wind and reported surface wind which makes it manageable to reach Vapp. Only disadvantage is autothrust activity increases.
