I am a bit out of the loop on the convo only reading back a few pages, but X94 was generally more expensive than GSX1 because of difficulty to find in NM or better, with a nice wrap, and white pages Back in 2009 or 2010 when I purchased both of them, I paid nearly $800 or $900 more for the 94 as it was much more difficult to find in CGC 9.4 than the GSX1. Once pressing became more mainstream, that changed the tide to GSX1.
Most current census:
X-Men #94 CGC 9.4 263
Giant Size X-Men #1 CGC 9.4 547
Now there are more collectors who collect keys, than collecting runs, which has hurt the 94 value.
