GX was the warmer version, while G was the normal version.
The description I've seen is that the process involved in redesigning the Ektachrome in order to take into account both market changes and supplier component availability changes involved:
- increasing sharpness slightly;
- increasing stability in keeping;
- improving (for Kodak's benefit) cold store keeping of the emulsions;
- adjusting the film’s sensitometric position so that the whites were whiter;
- adjusting the film’s sensitometric position so that the colors are more accurate.
The current Ektachrome is the best Kodak E6 emulsion to date. In terms of color fidelity, and ever standard measure. I have used a lot of Provia , E100 Ektachrome is a similar outstanding color fidelity offering. MHOFWIW
I recently developed a roll that I shot of colorful street pictures, came out beautiful.
E100G was the last version of Ektachrome before its recent revival as E100, a slight tweak of the same thing. The X version was a tad warmer, like using an 81A filter on either E10G or the current E100. I considered the regular or "cooler" version a lot more versatile. The current Ektachrome is perhaps their best ever from an objective standpoint.
I shot a few rolls when it was rereleased, in the day I tended to shoot Kodachrome, I think current Ektachome compares petty favorably with Kodachrome 64.

Different animals. Kodachrome was wonderful in certain ways, the current excellent Ektachrome nicer in other manners, especially the fact that it's available in all formats up to 8x10. But I never particularly cared for Kodachrome 64, at least in comparison to the 25 speed product. But going waaaay back before my time, I have seen a number of 5x7 Kodachromes from one of the best portrait studios of that era, and all I can say is, wow!
I have shot lots of old ektachrome and the only one that I found better than the new ektachrome was Ektachrome Elite II. Very good saturation and interesting vintage look. I processed in ECN-2 modified recipe though so its far different than what you would get with the normal chemicals. The modern ektachrome has insane sharpness and resolving power (increased by my recipe probably, I do all e6 in ecn2 as a negative.

That's a matter of taste? I need to break out my old slide trays and take a look at KC25, 64 and 200, compare with EK new old, 3M and GAF 100, 200 and 500, if any of the 500 are still viewable. I lost track over the years, did Ferraina ever bring market it's E6 film?
