That's a tough one. Ignoring the fact that it would be completely out of character with a Sisters army, I think (and clearly this is the weaselly answer) that it depends on the squad.
Dominions can be taken in squads of 5-10 women. If you take fewer than 10 you get 2 special weapons, but if you take the full 10, then you get 4. Their act of faith lets them twin-link their shooting attacks and usually works on a roll of 4+ (3+ if someone in the squad has died).
For the smaller squads, I think melta guns are still the way to go since those squads are usually used to destroy some initial vehicle target. In a hypothetical situation where you're shooting a Dreadought, two twin-linked Plasmas rapid firing will average the same amount of pens as two meltas (~ 0.6) but the melta wins out thanks to AP1. (Obviously if you're w/in 6" the meltas will clean house.)
On the larger units 4 potentially twin-linked Plasma guns are just nuts. I don't think I'd hesitate to play with one of those, add in a combi-plasma on the Veteran and you could have 10 plasma shots. I'd probably also pay 20pts for the wargear item that lets me re-roll faith checks to give me good odds to get my twin-link off. That'll pretty much kill whatever it hits.
