GEC uses 440
C.
Here is a review I did on the cutting performance of GEC 440C.
http://www.bladeforums.com/forums/showthread.php/730419-GEC-440C-cutting-performance
GEC 440C in and of itself, will outperform anything short of 154CM.
The 440C blades, with their excellent edge geometry, will outperform many 154CM blades.
For cutting performance, GEC blades will outperform any Case, any 420HC Buck, etc.
The GEC 1095 outperforms Case CV. hands down.
The GECs are nice enough that you could just collect them, but if you choose to use them they will outperform just about anything else in the park.
