Any thing is better than stock Showas.
I think the word "Showa" translated in Japanese is "for show only" 
Interestingly, Showa monoshocks are very well regarded on modern bikes and are standard fitment on Hondas (like my VFR), Triumph, Ducati (?) and others.
Surprised me too.
EDIT: Reading the HRC site, Shows are used on the MotoGP Fireblade CBR1000RR.
