The soil drying out is more important than you think. As Pr mentioned about soil aeration being important there is also mineral uptake to consider. The mineral calcium is not taken up when the soil is wet, and actually requires dry soil. Since calcium is a major mineral for chlorophyll production, you will notice leaves will become more yellow during periods of heavy rain that last for days. Too much water, even with soil that is well drained is bad. Bananas do well though with lots of water; this I won't deny.
