For me, it depends on the pants. I tend to wear mens' pants, as they simply fit better. Women's pants don't fit right, they ride up, they bunch up, and if I get them longer than what I wear, then I end up walking on them and destroying them.
Granted, shorts require shaving, and my legs are rather pale, but the paleness I can overlook. Shorts, particularly Bermuda and cargo shorts, are roomier in the crotch and thigh. They're comfier in that regard, and I can throw them on easier than I can pants, which I'll get my leg caught midway down the pant leg and trip.
Thus, at least for me, shorts are comfy and easy to wear.
