It's a matter of personal taste, but to me the 72-spoke wheels look too "busy". They are stronger, so if your driving style is a bit aggressive they are a better choice. Of course they are more expensive, too.
I bought 60-spoke Daytons with stainless spokes from British Wire Wheel in 1991 and they are still on my BJ8 with 99,500 miles on them now. Yes, I have found a few broken spokes now and then, but the first one was not until 80,000 miles. I go for long-distance reliable cruising rather than performance.
I have a double-handful of chrome spokes that someone gave me a few years ago, if anyone is interested in them. Because of the chance of hydrogen embrittlement of the metal during chrome plating if they are not properly treated afterward, they are more vulnerable to breaking from fatigue.
