No doubt for me (747-400 driver) ... has to be headwind to short final and then a light tailwind (certainly if onto a dry and clear surface)..
If you have a 25kt tail at 1000ft, then your groundspeed is say 175kts vs 150kts IAS for final approach speed. This means you will need about 5x175 or about 900fpm RoD which will reduce the power required and help potentially destabilise the approach. It, equally importantly, makes slowing down from an intermediate approach speed MUCH harder.
Most aircraft can accept about a 15kt tailwind component
afaik.
