I just looked at the original post so I'm not sure if the results have been posted. Out of the 4 I only own the GR so I'll base most of this off of what I like best...
Overall
File 1: This was the least of my fav's... a little weak in the imaging; and a tad to syllabint
File 2: Really liked this one, nice and dark
File 3: Really liked this one as well, it has the most "punch" (listen to the kick)
File 4: has the most "air"
Depending on how hard the GR was driven I would say that more gain and less ouput could be File 2 or less gain and more output could be File 4
