Been using J5 for several months (185/60/14).
Previously on Mich XM2, same size.

J5 just slightly comfort...just dont know how long it will last.
XM2 also comfort, but the rubber gradually hardened...4yrs using, thread still deep.
XM2 wet performance too superb compared to J5.
After my J5 hardened/bald....i'll go back to Mich

Juz my personal review...others might differ.
