I once saw a C-5 and An-124 parked next to eachother at Oshkosh about 15 or so years ago. Both were huge, and indistinguishable as to which was bigger, but obviously the Russian carries more.

I had a couple other observations as well; First of all, the Russian main wheels are all in a straight line, one bogie directly in back of the previous. The C-5 had a more staggered main wheel arrangement. The reason was that the C-5 could carry more load over a soft ground/snow. If you think about it, that straight line arrangement of the An-124 will dig a trench before that last set of wheels pass over the ground, whereas the C-5 would be making more tracks, but would float more weight over unstable surface.

The other observation was the cockpit. I actually got into the cockpit of the 124 after waiting a half hour in line. Employed as a pilot by a regional airline, and was transitioning from a Shorts SD-360 to an ATR, I was shocked as to how antique the russian avionics looked. God they didn't even have paint on the attitude indicator brihghter than grey. (as I remember) And the Radar looked like a single color, monochrome giant tv tube. Seriously, the SD-360 looked modern by comparison, and the ATR avionics looked spaceage. My impression is that you could not make avionics/electronics more bland looking than Russians do.
