I'm sorry, my attempt to be funny seemed to have failed horribly. 

Both sigmund~ and fiddle~ do pitch tracking and sinusoidal analysis, i.e. track
partials in a signal.  Where fiddle~ uses a fixed set of outlets to report
various pitch info, sigmund~ reconfigures its outlets according to arguments.
Both fiddle~ and sigmund~ can give similar info, in fact it's almost the same.
I won't repeat these here, for this indeed check the help files. sigmund~
doesn't have an explicit attack outlet, instead you use the more "musical"
"note" outlet, which combines pitch and attack info.  The various internal
configuration settings of both objects are practically the same as well, some
are reorganized a bit( i.e. amp-range is gone in sigmund~ which instead offers
minpower and growth)

Obviously it's not that obvious. :) (I'm trying to be funny here again!) As I
see it sigmund~ doesn't have that many new goodies (except table analysis). It
seems to be more like a cosmetic rewrite to make it easier to use than fiddle~.
The number of outlets has been reduced and their meaning is clearer IMO. 

But under the hood I think it uses a better algorithm. In my experiments it
reports pitch faster and more reliable and stable than fiddle~. So if you can
use sigmund~ I would recommend it over fiddle~ as a replacement.
