closed vs. vented sub-woofer box


Ordered a 10" woofer from P.E. that was supposedly made for and refused by Klipsch. Great big shielded aluminum thing, $95. Also the 120 watt plate amp for an astounding $79!
It seems as though most of the P.E. verbiage concerns closed boxes, as well as some DIY sites. It seems the closed boxplots are a little deeper than vented. Is bass QUALITY better with vented?
This particular woof is:
FS 32.8
Vas 3.24
QMS 7.95
QES .21
QTS .20
XMAX .18"
Boxplot likes a 3.5 cu.ft. vented, way smaller closed.
So what's better?
