Another very nice, easy to learn and fun to play squad with quite a few aces up it's sleeve is this:

Enemies often ignore the Z's, making them nice blockers/finishers while both Kath and Palob are fairly tough. Along with the upgrades both are terrifying for the opponent, be it through sheer damage, the turret or focus denial. New players I introduce to the game always enjoy flying this build, because they find it fun with all the synergy.
Another idea would be to replace Kaa'to and the Z with another ship, but I think that they add a little diversity and even single-fighter blocking potential.
