The best server provider in Europe ...

[Gerbert]

Servers from Legionbox.com (https://legionbox.com/dedicated-servers/) and HostRound.com (https://www.hostround.com/hosting/netherlands-dedicated-server) are to my liking and I have to select the best one for hosting a forum, so what should I do?

I would recommend Exmasters.com EU Hosting to anyone that is looking to do some hosting, Personal or Professional.
The team running it always has a sense of humor in their blog and newsletter - but doesn't let that get in the way of getting the job done.
