Going on VW Driver mag road test results, as they're done by the same people using the same equipment under as close as possible conditions using real life figures, then there's very little in it 0-60 between the ED40 CS & mk7 PP 230PS (same engine tune as standard 7.5GTI). Even the in gear performance is reasonably close going from published figures, manual vs manual.
The first two gears are quite low and the CS doesn't produce full power until 3rd gear so it's not really any surprise 0-60's are very close with no 4WD to halt the rampant wheel spin. The VAQ diff can't stop wheels spinning if they're both pointing dead ahead and normal traction control will try and stifle the power at the wheels instead.
Once you're looking at 0-70 and above you'll see the numbers opening up a bit. By which time an R would have vanished into the road haze ahead.
I'm not sure how much extra torque the CS puts out under full boost but the 7.5PP has more torque than the 258lb ft of the 265bhp tune of the CS in 1st & 2nd (which is identical torque to the other mk7 GTI's) so the 7.5PP may well be a fraction quicker to 60 than a CS.
It's in real world driving the CS scores with its eagerness to rev; away from academic (almost pointless) 0-60 drag races the CS feels more eager and although there will only ever be a few tenths of a second in it until way after licence losing speeds are attained (all too quickly) but the bigger turbo'd car definitely feels more eager once the needle starts climbing up the rev range.
