Has anyone else made the jump from Michelin XM2's to the CR1?

A previous post mentioned that they're more quiet & comfortable than the XM2. Would love to hear additional feedback.

Price wise the CR1s are also a fair bit more affordable than the XM2.. For my ride (175/65 R15) they are around RM160+ vs RM220++ for the XM2.

Seems the threadwear is lower though @ 340 (CR1) vs 420 (XM2+)
