BAT VK 5i and tubes, how to chosse?

I live in a distant Brazilian city, I have one BAT VK 5i with sovtek 6922 tubes. I would like to know about 6DJ8 amperex bugleboy logo, made in Holland( $105/pair), and 6DJ8 Amperex Orange World Logo Made in Holland($30/one)
Do you think they match with my BAT? . Some people
said to use sovtek 6H23 in place of sovtek 6922, even so are cheaper than the 6DJ8 amperex, but I think
that valley to pay for better quality. Which the best choice? is there any DANGER to BAT with 6DJ8?
