Shooting longer subs on the Canon will substantially increase the thermal noise effect and as sub numbers increase the sub quality will decrease - without substantial cool down delays between subs ( which are not very effective in dslrs anyway).
For comparative purposes, the cameras would need to have equivalent thermal noise impacts throughtout the duration of the test.

Unless of course you're using the ASI1600MC which is an uncooled colour camera. Just like the Canon DSLR.
My point wasn't for exactness, just a rough real world example of two systems.
