Ooh...that'll open up some discussion. Here's my 2 cents having built clocks with both of them.
The IN-18's are larger but not by too much and have more elongated numerals. They are also a little cheaper than the Z5660M as far as I can see at the moment, but still around 35 to 40 dollars a tube! The Z566/5660M are a little rarer and some would argue that the digit shape is more aesthetically pleasing. With regards to failure, I've had more issues with Z566's than IN-18's but I don't think there's any significant difference between the two. I think the datasheet for IN-18's says 5 or 10,000 hrs lifetime, but I've ran tubes for a lot longer than that without any sign of degradation (make sure the clock you use has some form of cathode poisoning prevention, digit cycling etc). Were you buying a kit to put these in or building a clock from scratch?
