Yeah, I haven't looked at the stats of the guardian distributor yet compared to my grade 5 recharge A-rated distributor. From what I've compared to the power plants though, the guardian power plant is just about equal to the regular power plant with grade 5 overcharged without an experimental effect. So it's not too bad on power plants at least.
Still, I think the guardian modules should be equal to the human equivalents in stats with all the work you put into unlocking these modules and the cost in credits.
There are two pics with GPD stats in this thread - for G4 and G8. The
only stat that is comparable to G4\G5 charge enhanced PD is recharge rate. Everything else - capacity, power draw, weight, cost - is significantly worse.
As for powerplant - for example, G4(!) overcharged 8A PP gives you 47.88 MW and -20%\-8% heat efficiency (without\with Thermal Spread experimental). Class 8 GPP gives you 47.5 MW and -25% heat efficiency. Of course, overcharged PP has less integrity - but if you need integrity, you should do armored mod (G5 of which gives you 40 MW, +12% efficiency and lots of integrity - and it weighs just 3 tons more than GPP).
And don't forget that GPP costs more than corresponding A-class "human" PP, which means it's a bad idea to install it on PVP or PVT ship (due to increased rebuy cost).
So no, it's not equal.
