So I have been trying to figure out which one I want to use from testing and looking at the code I can see that Power Surge regens 33 energy in 1 turn and Deflector Regeneration is 40 over 4 turns. On top of that with maxed out intelligence Deflector Regeneration seems to give about 47 shields per turn when wearing the reaper shield and Premium Armstrong Suit while Power Surge give about 144.
So from this Deflector Regeneration give more energy and more shields over 4 rounds yes, but is still better except for 1 thing. If you have full shields Deflector Regeneration will not trigger but will still count that turn meaning you will get no energy on that turn. This to me makes Power Surge the obvious choice as I will always get 33 energy and even if it caps my shield it doesn't matter.
This is really annoying as to me Deflector Regeneration sounds like it should be used when you have taken some damage but not a lot and want to top off your shields or you know you a large attack is coming and you want to allow your shields to regen better after. While Power Surge sounds like it should be a panic I need my shields back button. Yet they work nearly the exact opposite to get the full effect of Deflector Regeneration you need to wait for low shields when you are most vulnerable while Power Surge can be used whenever you need more energy or shields.
TL : DR Power surge is better because it is consistent.
