I see what you're getting at, but it's really the bigger wall of lows, whereas the Marshall has this gurgly low-mid sound, that I also would usually cut out with an outboard EQ...probably in the 270-400Hz range... Almost vocal 'ohhh", but just below that.
I'd say that the Diezel is more punchy in this case, because it's a bigger punch in the gut, opposed to cut-throat.
And even Euge himself has to admit at 9m10s that the Diezel sounds better here.
