Pani I used the Shuguang BT for 2 1/2 years. It's a good tube but I find the EML(XLS) better across the board. It isn't embarrassed by the Takasuki in my amplifier. The Takatsuki is the best sounding 300b tube(sublime) I've ever heard, unfortunately it's also very expensive. I haven't heard the "vintage" type WE but did try the WE reissue version. The Takatsuki and EML were much better sounding in my system. The EML though not inexpensive offers high value for the premium sound quality it provides.
