Hi

The 3801 is a pretty good box. In some cases I have seen them take months to achieve full stability. The "leave powered on at all times" rule definitely applies to them.

What I'd really like to do is to make up my mind based on educated opinions on this list whether the built-in OXCO option offers any advantage at all compared to standard clock + good external reference.

True there is no Lady Heather but it comes with its own sat monitoring software.  His site says he’s sold 20 and has four left.
