Wrong, and I'm surprised u/Threef and u/Cinco4706 are suggesting this is the case.
Recruit Repeaters cannot be powersurged. They will always stay at T0, for 10 Power.
Twin Suns have a 90 power advantage. This amounts to a power modifier bonus of about +.257, which seems like a lot but there's a HUGE problem with Twin Suns kit.
Recruit Repeaters will hit for 150MV/shot.
Twin Suns will only hit for 90MV/shot. Even with its crit empowerment kit bonus, that's only hitting for about 108eMV/shot. When we apply its power modifier bonus, it's only hitting for 136 damage on average per 150 damage the recruit repeaters deal. You spent $10 to deal 10% less damage on average than recruit repeaters.
And I highly disagree with the notion that Twin Suns have a lower skillcap.
Edit: Just read back, user mentioned lvl 4 (I assumed 40 power repeaters)
I also worded that poorly. I meant at a lower level people will do more DPS with Twin Suns, so they have lower entry barrier (based on data). They do underperform compared to other repeaters late game though, as everyone has mentioned.
