Having had RE050's as my last set, and have Falkens now, I would say that there is not much in it (according to the way I drive). My decision to put Falkens on was mainly due to cost.
The wear on the Falkens is good, I would have expected the rears to have worn down more by now. I did find they took a good 400-500 miles to settle in.
Next time round..... if funds are available then I will put RE050's back on, if not then I would still be happy with Falkens again
