Power Ventilation vs. gravity roof vents?

hey guys, still prepping for my adventures into better ventilation in my attic. Do you think that a power roof vent, is worth it? I will be installing the airscape 1.0.

I was thinking if I were to install a power vent, I would also install some gravity roof vents. I was looking at them, do you think that the plastic is better than the metal vents? Thanks!

If you have soffit vents, I would install ridge vent. It isn't "gravity", but convection of the heated air upward that evacuates the attic of the hot air, drawing in cooler air in from the soffit vents. Power ventilators require maintenance, and motor replacement quite often, because they are in quite a hot environment. Besides, they use electricity, while the ridge vents are passive.

I have a story and a half, so a ridge vent is kinda out of the question. It would only vent the small triangle above the room. Which does need to be vented, but I need to vent the area to the left and right of the room for now.
But thanks for the info on the power vents.
