Is the Babolat APDC lighter or less stiff than the APDGT?

I was wondering because when I swing with the APDGT then pick up the APDC it swings pretty fast and I feel I can crack the ball faster.

That was my experience. I definitely lost racket head speed when I tried the GT and I also felt it in my arm more than the cortex.
