Best sounding version EL84/6BQ5?

Amperex Bugle Boy it is europeean tubes made in holland looks like philips ,i do not tested.
Telefunken EL84 is not for me ,so expensive,never buy these.
Beware new production Telefunken ,with black letters on the tube,these is JJ tubes renamed nothing to do with NOS Telefunken
If you want to very good sound diy amplifier try the RH84 single ended schematic.
Good night from Greece!

Final word here.
Yesterday a arrive pair of Amperex Bugle Boy.
Very subjective, at the placebo level - they play more volumetrically. More holographically.
The bass of 6P14P-ER - seemed more impactful then standart stock 6P14P 80s years, I put them first.
I left Amperex.
 
Add pictures.
And sure great thanks to all, who help here.
