As everyone wears out tyres differently - you know different weight, pillions, luggage and riding 'style', road conditions etc etc etc. What works for one may not work for another.
But, in my case, I've loved the MEZ4 (now roadtecZ6) on the rear and an M1 on the front - although I'm now looking for another front I'll probably stick with the M1 up front.
While the M1 on the rear was absolutely fantastic it wore out in under 8000km (5000miles). Whereas the MEZ4 has been on for around 2500km and shows little sign of wear. I haven't lost much, if anything, in the way of tyre performance either. The M1 on the front has around 11000km on it and has another couple of thou left in it.
Bear in mind that going by the 'chicken strips' I appear to be pretty harsh on rears and fairly gentle on fronts. I've got around 5-10mm (.197 - .394 inch) on the rear depending on how long it's been since I had a play and around 20-30mm (.787 - 1.18 inch) on the front.
