I have the Fillmore and am a big fan. But the zero loss of pressure with Clik and the easier on-off mechanism will get me to try it. If it works as described, I might convert all bikes.
My issue with the Fillmore and regular Presta is the loss of air when I attach or remove some pump heads. The former increases air exchanges which leads to sealant drying out sooner. The latter means I don’t know the exact pressure after I pull the pump head off, if there is leakage. One of my Fillmores also has a bent core stem which gives me a lot of resistance screwing the cap on.
It looks like Fillmore still has the better anti-clog design while Clik improves the pumping process.
