As the title says, which do you think is better? Armored Gyros add 2t for a standard gyro, 1t for Compact (on top of the +50% weight of the Compact Gyro) and 3t for XL Gyros, which counters the weight loss the XLG grants.
Conversely the HD Gyro doubles weight for about the same effect, with the real benefit coming from if you’re running something with a 1t Gyro like an Urbanmech become a 2t.
I read the rules and they seem to operate roughly identical to one another.
