I like both, have both, and enjoy shooting both. I've only ever carried a semi-auto.
That said, and all practical considerations aside (I'm sure 99% of the members of this board already know all the pros and cons of both, inside & out):
There's just something about a revolver that "speaks" to me, if you will. I can appreciate a fine semi-auto, and I'll buy one to fill a specific purpose. But if you were to ask me what was my favorite gun, it would be a revolver every time. Maybe it's the simple elegance? The curves? How it's loaded and unloaded? The appearance of ruggedness? All of that and more, I suppose.
