Slight composition critique on number 4. If you didn't cut off the bottom of the foreground bushes and left a little room, the image would feel more complete. Small thing but you'd be amazed at the difference.
I have always loved the Tetons, only seen them once, but their shapes are stuck in my head. My choice would be #3, it is different, it includes some of the lifestyle that you can jump into in the area. And it has such nice soft color in the sky.
