Which Soundproof plasterboard

[peteinnit]

Hi all,
Just a quick question re sound board. I was looking at either British Gypsum Soundbloc, or Knauf Soundshield Plus, but have also just discovered Siniat GTEC dB, which I can source quicker than the other 2. Is there any noticeable difference between the 3? Or is one significantly better? Any advise much appreciated.

Many thanks,
Peter

Differences are minimal to none.
How they perform is almost entirely dependant on how they are installed.
