I am trying to compare these two strings because they are claimed to be having nano-scale coatings.

Toalson: very good "soft" feeling and resilience but unexpectedly short-lived

Gosen: very durable with a "hard" feel, which is quite an opposite to what is claimed in Gut Map from the catalogue

P.S. strung at 22lbs on Gosen Aermet 3600 & Kimoni WP02
