Uh huh, but really who would you think will win out in a battle bet SM and AM?
Depends. There's a lot of variety in AM skitarii. The skitarii attached to Legio Invicta would win hands down against SM, due to a combination of being genetically enhanced, power-armored supermen themselves and their extensive experience fighting, among other things, elements of the traitor legions. Also in the 'win in (relatively) short order' would be
1) the skitarii that were deployed to Tarsis Ultra following it's destruction by Honsu, as each is effectively a SM terminator
2) Legio Cybernetica forces, as their standard issue soldier carries the same weaponry as a SM dreadnought does. Literally, they're interchangeable, since the dread is a derivative from them.
Suggest but not definite. We are sure SM does a lot of fighting both on offense and defense. I would still wager SM are better since they were designed to be better from the start.
I can only 'definite' double the total number of SM in the universe, but I can only 'suggest' about 23 to 1 or higher if each Titan legion and Ordinatus legion has the same number of troops attached to it, but they're stated to vary. As far as designed better, only becasue the Emperor says so. In real combat, most magii's tech gaurd designs, with the exception of the lasgun equipped ones (since retconned to hellguns), would give them a run for thier money and probably inflict heavy losses even if defeated.
However, as the posterboys of 40k, SM enjoy the power of marketing over the AM, who have no TT minis atm aside from tech preists, techmarines, and Titans, so SM will win most of the time due to magic asspulls and the AM suddenly unplugging their brains and obligingly charging straight into heavy weapons like khornate berzerkers, while leaving their own, up until now, effective weapons behind for some reason.
Adeptus Mechanicus: When it absolutely, positively, must be destroyed down to the atomic level RIGHT NOW.
