It depends on your specific needs.

If your palate can't tell the difference between a $50 bottle of wine and a 
$5000 bottle of wine, do you still buy the $5000 bottle because it must be 
better?

As I stated, the software echo can in Zaptel and the hardware echo can from 
Digium work reasonably well for their intended purpose.  If you need 
something more, then yes, these products are insufficient and you'll need a 
more powerful (better in your parlance) echo canceller.  But for many people, 
the free one works pretty damn well, so buying a more powerful ("better") 
echo canceller is a waste of money, rack space and power.

Yes, I am splitting hairs -- something that solves your problem where 
something else couldn't doesn't make the latter "clearly lacking" or 
"complete rubbish" across the board.  I took exception to your painting the 
Digium hardware echo can module and the software echo cans in zaptel as 
trash, as they work very well for many people.  They clearly aren't 
sufficient for your specific needs, and thus the Orion Telecom echo canceller 
is better -- and I stress this -- for you.  It's overkill for many others, 
and I'm willing to bet that it's still insufficent for others still.
