The Venator is quite an interesting ship; what you actually saw in Revenge of the Sith (Go, Sith, Go...) was them being used in spectacularly inappropriate circumstances. They are fast but not that agile, they are intended primarily as carriers, five wings to the Imperator's one, with a small number of main turrets- each upper surface beside the superstructure- of very heavy weapons designed to provide long range fire support to the fighter wing. The closest ACtA equivalent, stat- wise, would be some sort of Avenger-Apollo crossbreed, with the engine block off a Marathon.
The Recusant is supposedly a fast, forward arc heavy pack hunter, almost Drazi- esque; what actually happened onscreen was the mutual cluster- £^%& after both battle plans had come apart, neither ship at it's best.
Supermaneuvrable does seem far too good, or that date, for that class. How come they forgot to add it to ships with far heavier boresight armament? Outlier, a fluke in a fleet where several skirmish ships only have 1/45. Not too unhappy about the firepower of the thing- compared to the Ka'Tan and Ka'Toc, it's not a problem.
