Quietest 6922 type tube?

Just wondering... out of these tube types which tend to be the quietest;

1) Siemens 6922
2) Siemens E88CC
3) Amperex PQ 6922 White Label USA
4) Amperex PO 6922 Orange Label USA
5) Amperex Orange Globe 6DJ8 Holland

I've considered Telefunken but they are much more.

thanks!
