I also fish shallow water more often than not, but I certainly prefer spinning reels as they allow me to hole the reel in the palm of my hand with my thumb and forefinger grasping the top of the rod handle. Not only does this combat fatigue, it also allows me to deliver gentle taps to the top of the rod with my forefinger that give my lure a light twitching effect.
In the end it boils down to whatever you're most comfortable with.
