Best practice on old vs new Sync Config

I noticed there are now 2 ways to sync configs between hosts. Any recommendations: OK to leave both checked, or should only use one or the other? … I suspect some of my recent floating window menubar status item woes are due to the multi-mac sync, haven’t had time to run experiments though.

In fact I’m not even clear if a “preset” is a downloaded setting, or if it is any setting at all. I’d like a link to the right documentation page from the Sync screen to make sure I understand the terms and what mental model to use for making the selections.

the old one in general should not be used anymore, it has caused a lot of problems in the past. It is there for legacy reasons but I'd recommend to disable it.

The new one is also super experimental but is the one that will be improved further in the upcoming versions and might eventually become stable.
