Looking for people who have tried both - have been scouring the internet and the general consensus I have found so far is that:
1) PR2 > PR3 in the dry
2) PR3 > PR2 in the wet
3) PR2 > PR3 in terms of wear/longevity
4) Z8's are as good/better than PR3 in the wet and dry but I cannot find mileage reports. *EDIT* based on the Motorrad test data, the Z8 wears better than the PR3 (not necessarily better than the PR2 however).
I haven't seen any handling comparisons between them yet and would really like to know if someone noticed differences in tip-in, corner stability, straight line stability, road noise, comfort, road feel, etc.
I know some people have opted for the PP/PR or M3,5/Z8 combinations as well to try and even out wear. My stock BT-016's are pretty much gone and don't turn in for **** (190/50 was a really bad idea by Kawasaki IMO). I have to fight to keep the bike down in the corner at the moment so anything would be an upgrade really, but these are the top two choices for mileage for me as I commute on the bike on concrete freeway daily during April-October.
Thanks for any advice and pointers additional to the topics on this forum that have already been covered.
Also open to other suggestions, these are the two that I have narrowed down so far based on research but I'm open to other ideas as well.
