Sovtek 5751 vs. Sovtek 12AX7?

Anybody compare these two? I am having a heck of a time finding an overall better tube than Sovtek 12AX7 that came stock with Almarro A205a MkII.

The GE triple mica black plate 5751 has a bit more robust/denser midrange, which I like, but sounds a bit rolled off in extreme treble and a bit hard in upper-mids compared to Sovtek 12AX7.

RCA black plate 5751 has a pleasant, smooth, warm, round tone but sounds rolled off on top.

The newest Shuguang 12AX7 actually sounds pretty nice with very well-extended treble and smooth, focused sound, but in my system, the Sovtek has a better, "come-hither" presence and breathiness.

Unfortunately, the Sovtek 12AX7 does have a slight bit of glare and grain, so I'm still looking for that tube that has the presence and detail of Sovteks while having a bit less grain/glare.. Perhaps an Amperex 12AX7?
