I also run 22 and probably will for a while just to make sure the new version doesn't hard fork with the old version for a year or two, but I'll probably upgrade to version 24 when version 28 comes out.

To continue running an older version with the full rbf flag tho, I've started running Bitcoin Knots version 23.

I actually run two v0.17 nodes, because I haven't bothered to upgrade my OpenTimestamps server software to support new Bitcoin Core versions.

Which is fine! The great thing about Bitcoin is we do backwards compatible soft forks, not hard forks.
