Infomaniak would be the closest, from your big brother ๐จ๐ญ
We already manage your airspace and stuff, please let us have your data, pretty please ๐
Joke aside, Infomaniak is good, with green datacenter (no AC) that uses their heat for the Geneva hot water network.
But it is not the best from a price point of view. The neighbours do better on that point, France with OVH is difficult to battle against but Infomaniak brings the K suite and stuff for a "low" price point (low for CH/LI, not low for the rest of Europe)
PS: There are 7 datacenter but I believe they are hosting corporate stuff, so dedicated and bare metal hosting. Not individuals cheaper VPS. But I might be wrong https://www.datacentermap.com/liechtenstein/vaduz/
