I’ve used Gportal (the host of the Official servers that Funcom uses), and I’ve used GTX Gaming.
GTX Gaming is a few cents more a month than Gportal, but very much a better experience. Its UI is a little less user friendly, but it doesn’t glitch sometimes like Gportal’s does.
The customer service on GTX Gaming is also quicker. I’ve admined for a server that used it and the owner remarked several times how the CS rep would talk to him directly on their discord within minutes. of having a problem.
Gportal uses a ticket based system and can take a few hours to respond.
Both services will give you a virtualized box. Which for a few friends is more than enough. Adding mods is relatively easy for both (a little trickier on GTX due to the UI, but it will work). And I’ve found GTX actual server settings (changing idle food/water crafting speed, ect.) is a little better organized.
Both will serve your needs well.
I’ve used Ping Perfect for a Space Engineers Server. But not Conan. From what I remember their UI is very user unfriendly. Once you’ve got it, you’ve got it though. But other than that I don’t remember many issues. They do have a ticket based system that takes a minute to get a response.
