So for fun, and because I'm off school so I've got some time to burn. I threw out both omnitron's "perfect set-up", of all their components best plating ect. This sort of represents their "comic book power" as it gives them all their options all the time.
For omnitron I put out copies of interpolation, railgun, and disintegragtion, as well as adaptive plating. I did not count his drones of electro-pulses but I will make note of them. I also did not do nemesis bonus, I just didn't feel like it 
Repair drones don't do any good damage wise, but if all drones are out they would heal 10 each.
Automaton drones are generally pointless (omnitron deals mostly energy so Omni-x would equip elemental exochasis so Auto drones need at least H=3 to deal any damage)
Assault drones would be devasting, 10 damage each if all drones are out (30 total) this is also true of the electro-pulses if both were put out.
Interpolation does 0 damage (1-2)
disintegrationg does 0 damage unless h=3, in which case it does 2 total ((3-2) *2)
railguns will do 2-4 depending on h (an h-1 I said could not end up below 1 damage)
so if we do not count drones and pulses we get omnitron dealing about 6 damage at h=3, any lower and we have 2 damage. If we count the drones and pulses and set h=3 he deals about 69.
Omni-x
would have reactive plating in play, so deals at least 2 energy damage, perhaps more depending on if you count complete cancelations and you bother hitting drones since omnitron is immune to energy after the first hit
Start of turn omni-x has 2 electro deployments so he can play 2 cards without sacrificing anything to his big cards at this point 2 sedative fletchettes would be useful, killing all drones in play (if we put them there) and destroying adaptive plating. 4 damage
2 plasma cannons deal 4 damage
2 gausian coils deal 2 damage (and could hit 2 other things if other targets still exist)
omni-x gains 2 hp from innervation (could also heal 4 other targets if so desired and if they exist)
play slip through time
use defenseive blast for 4 damage to everything
use defensive blast for 4 damage to everything
play self sabotage, destroy all of own and omnitrons components for 28 damage
Total damage to multiple targets would be about 14 or so damage (enough to kill or at least neuter the pulses)
to omnitron it would be about 48 damage
So, if X strikes first then he destroys or neutuers omnitrons entire field and hits him for almost half his health.
If omnitron strikes first without his drone army and massive bombs (and we set power at h=3) he has enough damage to destroy X's components and severly neuter the rest of his play. If h does not equal at least three omnitron does negligible damage. If he brings to bear his entire drone army and massive bombs he destroys X quickly, which makes sense if you have 1 guy vs an army.
So, straight up 1v1 with all components X rips omnitron apart. If omnitron can use his army then he wins, of course, then it isn't 1v1.
While doing this my Darkwatch promos finally arrived, so I'm going to go enjoy them for a time
