Amperex tubes questions

Hi,
I am about upgrading my SFL-2 tubes and got an offer of Amperex :
1. 6DJ8, orange labeled, made in holland, PQ, A-getter, non-gold pin.
2. 7308, white labeled, made in USA, no "PQ" marking (no shield mark too), gold pin.

Does anyone knows differnces between those tubes, sonically, lower noise, etc? Thru my search on the internet, I rarely found the information regarding the white labeled but no PQ mark amperex.
Thanks so much
Regards,

I have a pair of Amperex 7308 USN-CEP's that I sometimes use in my Audioprism Mantissa preamp...very nice from top to bottom!

The 7308's are for someone not wanting to much of a good thing IMO...if your looking for lots of color, it's not there.

Thanks so much for the help.

PS. To Dogpile, actually I am not sure whether it's A "frame" or "getter". I just use the word "getter" as that word was used to describe some of the amperex tube by some sellers.
The labeled on the 7308 is mostly unreadable. So I could not confirm whether it has "USN-CEP" label.

Once again, thanks so much
