Yes, the Hyperfire's ROF is faster than the RapidStrike, with both Alkalines and IMRs. In fact an overvolted RS using a pair of IMRs has about the same ROF as a stock HyperFire on alkalines.

However, if you plan to do any modding beyond battery upgrades, the RapidStrike is a way better choice. The NIC is full of Stryfe/RapidStrike mod kits, motors, flywheels, pushers, you name it. I don't see much of anything for the HyperFire. It also doesn't help that it lacks barrel and stock attachment points.
