I've heard of both being used as dampening material.

I have a hard time believing there isn't a clear winner between the two simply because of the huge differences (putty vs sheets). Anyone care to speak a little on the subject?

What exactly are you using them for?  The Dynomat is typically for damening inside headhone shells and other internal components done on modded highend Denons (search Lawton) and Ultrasones..  The Blue-Tack worked wonders in stopping the tube microphonics with my TTVJ Millett hybrid amp.  I've read that DIY members used the Blue-Tack to mod their lower end Grados (SR325 and below).  Asking which one is better is a little complicated due to their intended purposes as in most applications, one cannot substitue for one another.

Blu-tack for rounding corners or forming cones if you want to.
 
Dynamat for laying out in sheets.
 
 
Apply blutack for corners and apply dynamat over the entire inside to create a nice and dense smooth surface.

I actually had intentions for both the Markl mods for Denons and the grado driver mod. I'd hate to buy both products.
