After running the numbers on SG with the new changes for 9th I figured I'd compare our 3 elite melee units. These numbers are based on 1 model charging and all are equipped with a jump pack for the points, with no extra auras/buffs factored in. For the points efficiency it's simply model points / wounds dealt and I've set the chart scales the same for easier visual comparison.
My main thought is that SG are very strong overall. As I mentioned in the SG topic, getting that extra base attack makes a big difference to them and the fact that all their weapons now do a flat 2 damage makes them nice and consistent. Their weakest area is points efficiency vs 1 wound targets, as the 2 damage weapons are overkill.
When you consider that a SG with 2 damage encarmine sword and DC with 1 damage power sword both get 4 attacks on the charge and both cost the exact same points I honestly see no reason now why I'd take DC with many of the weapon choices, even more so when SG have the angelus boltgun included at the same cost.
You could say DC will still shine with a chainsword for chaff clearing but take a look at VV with lightning claws. Even 1 claw is stronger than a DC with the chainsword thanks to the wound rerolls, and a pair of claws is not only the most efficient by far against chaff but also maintains reasonable efficiency against tougher multi-wound targets.
Where DC do have their niche, for me, is with the thunder hammer. The extra attack over VVs gives them the highest potential damage output when you really need something dead but they are the most glass cannony option.
For a resilient unit against tough monsters the VV with a hammer is certainly an option, though adding the cost of the storm shield reduces output efficiency by ~11%. That model then becomes more expensive than SG with a fist (37 vs 35) and actually does less damage, so is a fair bit less efficient from a damage output perspective. The resilience then comes down to the SS giving 2+ / 4++ vs the SG having their native 2+ save and -1 to hit, though admittedly the SS works against shooting.
As a short summary, I see the following stand out options:
Overall Versatility: SG with Swords
Chaff Clearing: VV with Claws
Maximum Damage vs Vehicles: DC with Hammers
Resilience vs Monsters: SG with Fists or VV with Hammer + SS
I'm not seeing any real benefit to the humble power sword in any role, unless you're up against a Sisters army where DC with a sword get close to the efficiency of VV with claws.
And finally, if you were looking to run the units with a warlord, SG would pull even further ahead with the Heirs rework.
