My next design (if I get round to it....) Is going to be using a st microcontrollers clone (made by gigadevices - gd32e230c8t6) and discrete HV transistors for Nixie driving.
Cheap and available from JLCPCB as pre fab designs. Can talk to it via spi as well so drive similar to the HV chips if needed.
