2019 300B tubes that are worth the money?

My previous tube mono blocks used the 6SN7 as drivers and I used vintage Syvania and RCA. They were early to mid 1950s. The 6EM7 driver (1950s) and Mullard rectifier (early 1960s) tubes in my current 300b SET are both vintage and very good. I personally would not paint with a broad brush in regard to vintage tubes. There’s a wide spectrum of performance among them and all are not superior to current production tubes. Multiple factors to consider.
Many current production 300b are available and some are simply superb. Gary (gsm18439) made this observation in a post above and he’s absolutely right. Takatsuki, Elrog,KR,EML etc. can certainly hold their own in terms of sound quality and conveying musical beauty and truth..

There are awesome and for $100 more the Carbon Plates are even better.  Sophia makes awesome tubes for the money.

Aren't Sophia tubes just rebranded TJ Full Music tubes in which Sophia claims to cherry pick the best for the US market?

I believe Sophia Tubes are made by TJ Fullmusic and years ago it may have been the case that the cherry picked. Now, Sophia has a bunch of products that are exclusive to Sophia that I can’t buy directly from TJ and no one else will have.  Sophia tubes are exceptional.  

I have reached out to TJ to make a purchase - the issue is you need to make a large purchase and I am waiting for my traffic for tubes to build before I commit to that much inventory.

Yes Sophia are just rebranded TJ tubes and have a bad rap for reliability. I have only had a few tubes fail in my audio life and they have all been Sophia/TJ. I also have numerous friends that have had problems with Sophia 300B.  Buyer beware.
