It doesn't matter that much, but I like Arch... it's a bit of a pain to install if you are new to Linux though. I find it more stable than Manjaro though.
Your decision probably should depend on if you like KDE or Gnome and if you want the latest software or something a bit more stable.
You could also try the live version first before you install it to make sure everything works as intended.
Google, for example, did many demo websites that only worked on chrome in the past... I've also seen government website that only worked in Chrome... but unfortunately I don't keep a list. A company I worked at in the past also had a training website that only worked in Chrome (I'm not revealing this one though...).
Edit: Just stumbled on this website: http://Thai5sushibar.com ... not sure if it's my extensions, but it doesn't load in Firefox and loads in Chrome. Good rainbow rolls.
Even at 47%, it would still be the country with the highest percentage of Jews, no? (if true, which I don't think it is according to other more credible sources) so I don't see your point
thanks
