One advantage that biquinaries still have, that they use a common 9-pin socket, that you still can get easily. But their real advantage disappeared with wide use of ICs. Back when circuits used discrete parts, then driving a set of bi-quinaries would use fewer parts. Think a flip-flop, and a 1-of-5 decoder, or a 1-of-5 ring counter. A regular nixie would need a 1-of-10 decoder, or ring counter. But when ICs came out, they came as 1-of-10 decoders (7441). You still needed one per nixie, if it was a normal type, or a biquinary. My first nixie clock used bi-quinaries, and it was multiplexed. It has twice as many anodes, so it was actually more complex, than if I used common nixies.
In short, if there's any project that you want to use for this type of tube, it would be an all-tube clock, or discrete transistor clock.
