I've found significant differences between new production 5U4s and OS Tung Sol, GE, RCA and Sylvania. My preference is the TS 5U4GB.You want to avoid any 'made in USA' Amperex tubes as a general rule (though there are exceptions). Most of these are rebranded tubes sold by Richardson Electronics, who bought the rights to the Amperex trademark. As far as I can tell, Amperex 5U4s are actually GE. But your brown base is interesting. Do you have one of the British tubes from the photo?
