> would you say "always use gc:arc" is a safe bet?

This is the first release to offer `--gc:arc` so there are still some rough edges, but I would follow @treeform's and @rayman22201's advice from sibling comments: give it a try, it might work for you without any problems, and if not - report it.

The long-term plan is to make it the default.
