Now this came as a surprise to me because I had always grown flytraps in sitting water and it never seemed to cause any issues for them.
While flytraps can sit in water all the time in some warmer climates and rarely have problems, it is much better for them to keep the soil moist rather than soaking wet all the time. As you wrote above, it stimulates root growth, which allows the plant to grow to a larger size. Also, the risk of disease is much higher when flytraps are sitting in water all the time. Here in Oregon where our nights are rarely above 50°F, even in the summer months, many of our flytraps will succumb to mold and crown rot if kept too wet all the time.
Other growers around the US and world, typically in warmer climates, find great success leaving their plants sitting in water all the time. But the biggest flytraps I've ever seen were growing in a warmer climate and were expertly watered to keep the soil "just moist" most of the time. They were exceptionally healthy and developed very substantial roots systems and the biggest rhizomes and large leaves and traps I've ever seen.

So my question is, has anyone ever had any experience with this type of thing? Is it better to have longer roots or does it matter?
Sarracenia seem to be less concerned with the moisture level of the soil and will usually fill a pot entirely with roots even if left sitting in water all the time. It seems to me that the size of the pot determines the root length rather than the moisture level.
Though Sarracenia can develop very elaborate root systems too, which can lead to larger and healthier plants, they seem to be able to grow very large and vigorously regardless of how wet they are kept. They differ from flytraps drastically in this way. Though, that same grower that grew the largest flytraps I've ever seen grew his Sarracenia the same way and they were large and gorgeous too. However, I've always grown ours by putting them in 5 inch pots and keeping them in 2-3 inches of water and they rarely have any health issues, other than in winter (mold), and grow very elaborate root systems even in the water they sit in. I've never seen a Sarracenia stunted or unhealthy from too much water, but I have seen them not grow as vigorously when not receiving as much water as they want. I'd err on the side of more water for Sarracenia and less water (though always moist soil!!) for Flytraps.
