So far, worst has been Michelin anything (Energy, Primacy and LTX). Short life, high price, and IMO poor performance in snow (although great in rain). [Although Nokian i3 were downright scary in wet, was glad to be done with them; WR's wore fast and got noisy at the end so they weren't great either.]
General RT43's have been a good middle of the road if not downright great, when everything is factored in.
Best? I think Nokian entyres might have been best, for me.
