Didnt have much experience with dedicated servers but scalacube was very simple and eficant, with a server of 4/ players we didnt have any problems with any kind of server crash, we had extremely punctual lag a few times but it gets fixed inmediatly, really good experience if u want to play anytime, definetly better than realms
