If you're talking about transconductance,

Ya, because they have that fun little exponential Vbe curve. Beta is to
transistors what Gm is to tubes and FETs, and you know it...

No, transistor Gm is to tube Gm as...

Good transistor design is beta independent, as good tube design is
tolerant of variations in transfer curves, grid current, and
transconductance.
