Best package for typesetting critical edition of Greek texts: ednotes, reledpar, reledmac, or ekdosis?

I know of several packages designed for producing critical editions: ednotes, reledpar, reledmac, and, most recently, ekdosis. What are the relative strengths and weaknesses of these packages for producing critical editions of ancient Greek (or other) texts? (E.g., initial process of producing the content, typesetting facility and flexibility, compatibility with other packages.)

The documentation of each package offers some idea of why to choose one over the other (ekdosis, for example, stresses its compatibility with TEI-compliant XML output), but I am hoping to hear from someone who has experience producing critical editions (or who wrote/maintains one of these packages) and so can speak to the advantages of one or more of these packages (or another package) in practice.

To be clear, I am including below a screenshot of a page from a critical edition of the sort I am describing (from Ihor Ševčenko, ed., Chronographiae quae Theophanis continuati nomine fertur liber quo Vita Basilii Imperatoris amplectitur, Berlin 2011). It demonstrates some of the features required: marginal line numbers, page numbers of other editions, folio numbers of manuscripts, multiple footnote registers that are keyed to line numbers rather than using a footnote hook, etc., as well as parallel translation.
