I have a HD800s, I like it, but for actual daily use, I wear my HD599 and HD650 much more than my HD800s.

I would say if you live alone or are often alone and absolutely love to listen to movies and music, go for it.

But if you mainly listen to YouTube/podcasts, live with others that don't want to hear your super sound leaking headphones, then you're spending a lot of money for something you might not use much compared to your current headphones that aren't picky about the source and leak sound way less. I think people underestimate diminishing returns and the daily usage practicality of headphones that leak sound as much as high end open back headphones do. But if you've got the funds, it's not a big deal if you aren't using them daily. Your mileage may vary.
