The auto-wipe gap is a bigger deal than it sounds
Rust isn't a set-and-forget game. A server's population lives and dies on the wipe cycle. Most run a weekly or biweekly map wipe, and the first Thursday of every month is a forced wipe when a Rust update breaks blueprints. Hitting those wipes on schedule, at the right time, is most of what keeps a server alive. Miss one and your map is stale and your player count craters on the exact night people are looking for a fresh server to join.
GameServerKings has no scheduled auto-wipes, which means every cycle is a manual chore: stop the server, clear the map and player data (and blueprint data on a force wipe), update, and restart, and you have to be there to do it. On a Thursday that often falls during a Rust update window, that's a job at an awkward hour, every single time, with real consequences if you're late.
How Physgun handles it
Physgun automates the entire wipe schedule, running map wipes on your cadence and blueprint wipes aligned to forced wipes, so the server resets itself on time whether or not you're awake. Pair that with scheduled restarts and one-click Oxide/Carbon updates and the recurring admin work that GameServerKings leaves on your plate mostly disappears. That, plus current-gen hardware over their older Ryzen and a 3-day money-back window versus their 24 hours, is the practical difference week to week.
