I have had both types on the Audi and a Merc I had in between and I genuinely prefer the LED's they are so much brighter imho nice clean white light which works better in rain and fog in particular. The LEDs have a rain/fog setting on them which lowers and widens the pattern so works well.
I do fancy these matrix jobs and have been thinking of a change this year
If funds allow I have been considering the latest S8's
It looks a cracking bit of kit although the V8 D offers such good value and on paper doesn't look lacking.
Cheers Glyn
