2019 300B tubes that are worth the money?


OK, I'm not a super rich audiophile that has unlimited money to blow.  I have a pair of Cary 300 CAD300-SE monoblocks i bought used that currently have a pair of TJ/Full music tubes in them.  I am, overall, very happy with the sound.  So does anyone have a strong opinion that any of the $1000 a pair current production 300b tubes are really worth the money over my $300 pair?  Would my money be better spend on a needle upgrade for my turntable?  :-)

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.
