What is best sounding depends on your personal preference. SC with T900 will probably be louder.
I don’t know what the GR Bass amp sounds like.

It is not 100% sure what is louder. When I had 2*10 Cabs in the past (Ampeg svt210he or TC rs 210 with Aguilar th500, Ampeg B2r) I was Happy with the power and loudness of those gears. I know the sound of tecamp and eich amps but not how grbass sounds. I red that gr bass sound more like a solid state amp, this is good in my opinion.
Thank you.
