I am also using the Takatsuki 300B, have been for a bit over a year now. Magnificent. Even though I am very fond of the EML XLS and mesh (and thankfully it is a true mesh, not a cheap punched plate like the TJ) and at times some of the KR variants (I have a straight bottle pair here, and a few others) the Takatsuki is king. But for those looking for something less expensive, do check out the Psvane and Shuguang Treasures 300B's - I have been listening quite a bit to the low priced Psvane 300B and after a very long break in it is really very nice, and totally makes the TJ sound like mush (which it is).
I might try the Psvance WE 300B replica which I have every reason to believe might be killer. Had to get past all my decades of preconceptions about Chinese tubes, though.
