My opinion is that there's many levels of server security to consider, from physical security of the hardware itself all the way up to secret state surveillance and many technicalities when it comes to legislation.

From a glance it looks rather comparable, standard hosting stuff, reasonable privacy laws and no publicly known secret courts to issue search/monitor warrants.

One of the Swiss providers talks about "Swiss Federal Data Protection Act and Ordinance to the Swiss FDPA, which gives judges the discretion to restrict data access without substantial evidence of a crime." (https://secureswissdata.com/swiss-secure-hosting-laws/)

which leads me to guess there's some sort of default data access?

I can't really say what's legally or technically bad about Swiss hosting, only what's nice about Norwegian hosting.

Edit : Swiss/Belgium is not about EU laws, I consider both countries highly suspicious from a conspiratorial angle. Personally I'd rather have it in Guatemala or something rather than Switzerland.
