It's pretty much the same as the Nemesis-class....clearly better than its 'parent' hull but not twice as good.
84 crew - the 'defining' damage track - is one short of a Warlock. However, the Warlock only has 75 non-repairing hits, making the Shadow Omega just a fraction tougher.
Self-repair means that (in theory) the Shadow Omega will be de-crewed before it's crippled - so there's no risk of it suffering crippled benefits, hence won't lose its flight computer, hence won't be skeleton crewed either. Few ships fight at full effect until destroyed, but the Shadow Omega should - and also shouldn't explode, either.
The active defences are a touch better - Anti-fighter 8 and Interceptors 6 rather than Anti-fighter 6 and Interceptors 4.
The Best of the Best special rule means that you can more readily pull off Come About! (for 90' turns - good for lumbering ships), Concentrate All Firepower! (if you only have a target to one flank) and Scramble! Scramble! to get those 'bolts out of the hangar. More importantly, it stacks with Self-Repairing, to give you a +2 on critical hit repairs - meaning that All Hands On Deck! should pretty much clear everything automatically.
Although the Warlock has a Command +2 boost that the Shadow Omega lacks, a Psi-Corps fleet has a default initiative sufficient to cover the difference anyway.
The broadside firepower hits about twice as hard - if you can fire along both flanks at once, a Shadow Omega can deliver quite a beating to lighter ships.
That said, it still always comes back to that rather feeble 18" range on the forward beam. It's not exactly crippling; it's the same speed as a Warlock, so one turn at max chat covers a full foot - you're unlikely to miss more than a single turn of shooting (admittedly no boresight shots when doing so). Unlike normal EA destroyers, a Shadow Omega has to go barrelling in - Psi-Corps has more than enough ships to hang around at the back with (yes, we're looking at you, Mothership)
The big problem is that a Warlock has those bloody missiles and railguns to back up the main cannon, whilst a Shadow Omega has a mighty 4 light cutters, and - unlike a normal Omega, has no rear beam for once things start mixing it up at close range.
