Possibly, if the "secure enclave" of the iPhone is actually some sort of hypervisor that takes up processing power. In other words if there is an additional DRM layer there may be a performance penalty that equalizes the real world performance of the devices.
Although the battery life on LTE will likely be better. I'm not sure advanced gyro does much but track you more. Unless you work out often the cost benefit of privacy of potential always on gyro may be unattractive.
