Reporting question for Vacuum Tube - 12AU7, China

Product:
Vacuum Tube - 12AU7, China

Question:
I can’t find any information about this tube on https://www.amplifiedparts.com/tech-corner/12ax7-comparison-current-made-tubes. Can you compare this tube with Chinese 12AX7B with parameters like noise, low, mids and high? Will this tube reduce Lows and Gain as well as maybe some noise ? Im planning to put this tube in socket V1 instead of Sovtek 12AX7WB
