HDR is the “marmite” of photography. You either love it or hate it. I quite like HDR myself and sometimes overcooking the HDR can work but it all depends on the subject.
Personally these are a bit overdone for me. If I had to pick one I would say my favourite is the 4th one but I think it is more to do with the composition and the sky than the HDR.
Might be worth revisiting these in the HDR software and toning them down a bit as compositionally some of these are quite nice.
If you take the first 2, it is extremely difficult to discern any detail in the rocks in the foreground.
