Vasari Exodus vs Vasari Alliance

Which do you prefer, which do you believe to be stronger? Obviously VE has the phase jump abilities on their Titan, basically a Kostura Cannon, and the mobility with the ship-bound stuff, also some debuffs to enemies and economic advantages. But the Alliance has quite substantial upgrades to hulls and shields, and quite a few other (planet, structure defense, the minor faction research etc.) gimmicks.
