I have both the Falari and Dalix caps.  Like them both a lot.  The Falari has a nicer clasp, but it's also a couple bucks more if that matters.

EDIT:  I purchased a Falari cap here 2 years ago.  Received a "Nissun" cap, don't know why, but it fit well (much like the Dalix).  So I ordered another Falari and this time actually received a Falari.  It seemed large, but I knew it would shrink a bit when washed.  Well, after washing turns out that the top section is still really large, just about floats on my head.  That makes a second inconsistency.  I will stick with the Dalix; less expensive, true sizing, equal quality.
