Supreme commander is better for necrons than marines, but costs the same. That's not a downside.
Sure it hurts more if he dies, but only because it's better in the first place!
Imagine instead of the SR bonus the necron SC gave an extra initiative reroll, so 2 rerolls. It'd certainly hurt the necrons to lose the SC more than it would hurt Marines, but does that mean it should be the same price as it is for marines?
No, because it's a lot better than the marine one!
Now imagine it made necrons SR10. By your logic it should still only cost 50 points because it'd be -9 SR when it died.
Your argument is really flawed, because you're not taking into account how good it is while it's alive.
Hyperbole isn't helpful here.
You haven't illustrated a single instance where the Necron's strategy rating has had a bearing on the existing list.
I've said it before, and I'll say it again: Playtest data is more valuable than theory.
You've said it yourself. The Abattoir for example looks like an abosolute monster on paper, but in action it's not as devestating as it might seem.
I well remember the screams of horror about the unit when it first came out... then people started to actually play it and all of the sudden the complaints were the opposite: that it was over-priced.
You've also overlooked something. The Necron have to pay 300-350 points to have a strategy rating of 3. The Marines get it for free. And I hate to break it to you, but realistically, the Necron are just as tactically capable as a the Marines are. Hell, their stats are virtually identical! The only reason I put in a variable strategy rating was to make the army a little more fluffy. Well, that and to make Supreme commanders a nice juicy target. 
play a few games with them. Win them, and show me where winning initiaive by less than 2 points turned the tide in the game a few times.
Then explain to me how that is any different from EVERY other game where winning initiative on a turn is the deciding factor in who wins a close game.
Then you should be able to demonstrate how that would be broken.
