I have had a few of these used, which showed quite severe cathode poisoning, 
but I was able to recondition them with cycling the digits at higher current 
until they shine like new again.

I'm certainly not expecting 40+ years of continuous operation from any of 
my tubes, but if that's what you've getting I may as well give it a try and 
run my 7971's 24/7 .  I assumed that bigger tube + more pins + more 
interior surface area & materials would lead to significantly shorter 
lifespan.

My favorite: Burroughs 5092. Small (0.6" numbers), but very reliable. I've 
never had one fail on me, and I've never encountered a defective one via 
Ebay.

I have clocks with other tubes (6091, IN-18, and coming soon, b7971), but I 
can tell they dont have the same ruggedness.
