The other big issue with Nixies is the high driving voltage needed. I
remember the 7440 (?) binary to 10 output decoder, capable of handling
Nixie voltages. But those were always expensive.

7 segment displays took care of that. Not just the LED ones, but
(somewhat earlier still?) the incandescent wire types. Those didn't
stay around long, but in the early days were preferred because they
were cheap when LEDs were still very pricy, and very limited in size.

I still have a somewhat-working rack mount counter-timer with Nixie
displays. Should spend some more time on it, I could use a frequency
counter and this one may serve...
