Everyday's a school day on here, I didn't realise some of the same model cars had different LED patterns/reflectors etc. I had Adaptive LEDs on the 340i and also have them on the F10 M5. I am sure that they are better on the F10 (however the F10 adaptive LEDs aren't quite as good as the same system on the W212 facelift E63AMG), but I only had the 340i for about 8 weeks so I don't remember too well.
The LEDs on the F10 (and F01) really lift the front end of the car aesthetically, IMHO, particularly the 7er. There's a black SE that I see opposite work a lot that has the LEDs and it looks really quite desirable.
I was always quite happy with Adaptive Xenons on previous BMW cars; I used to throw the E90/E87 into corners to 'see the front lights move'. I think the Xenons on the S2000 were sharper/brighter than any of the BMWs I've had, though.
