Well for now, I will stick to my P1S in addition to the H2D. I cannot replicate everything I achieved on my P1S on my H2D for now. For example, I use a lot of Matte PLA and on my P1S I can achieve injection molding quality ironing that I cannot replicate yet on my H2D whatever mods I make in my filament profile or the slicer. As long as H2D firmware, filament profiles, etc are not fully optimized, my P1S is my reliable printer. Of course for engineering materials, multicolor, multimaterials or oversized models my P1S cannot compete. Long story short, I need both for now and when I play with settings on the H2D, I can print on my P1S 
It’s not just that. To make it simple, I would use this analogy: A bigger hammer added to the toolbox does not replace the smaller hammer. It’s one more tool in the box which is good. But there is something about using a hammer that feels just right for the job.
Our perspectives can be different (not right or wrong, just different). That’s why I started with “In my view …”
I didn’t intend to make you doubt about the H2D.
Energy consumption is one thing. Another is the loss of some speed/acceleration due to a heavier print head. H2D’s complexity in incorporating laser cutting/engraving can lead to more opportunities for problems and error messages to arise. If the print doesn’t benefit from H2D’s features, one can also have the feeling of using a hammer that’s too big for the job, like the above analogy
But you only have the space for one printer. So H2D is the one to keep in your case. Enjoy the printer.
