Three Premium cameras, which one gives the best HDR result?

Typhoon "Egay".  Shot with a Coolpix A.

I went to Lubao, Pampanga, to see the Balloon festival, and of course to test my new G1X Mark II.  It was a bright and sunny day, and therefore, it' was a great opportunity to put the camera through its paces.  All shots were taken in P mode and in JPEG format.  I check to see, besides the base output quality of the camera, its "Tweakability" in post processing to see if their Jpegs would be easy to edit.  These pics were edited in Photoshop.  Nothing fancy, just some simple tweaks in their Levels, some sharpness enhancements and that's it.  Some cameras are better in their OOC pics, and would worsen if their photos would get further post processing.  How will the G1X Mark II do?
