In earlier posts, I have shown that BHQ and OHB in sample form, while carefully done, provide an incomplete picture of the textual data in hand and are occasionally guilty of sins of omission and commission with respect to treated loci. The upshot is clear: BHQ and OHB are tools to be used alongside other relevant secondary literature and must be checked against the primary data. They do not replace either.
It is also true that BHQ and OHB represent a radical improvement over BHS. Both (will) belong on the shelves of serious students of the Hebrew Bible.
A truly satisfactory edition of the Hebrew Bible for the purposes of text criticism would be electronic in nature, and include hyperlinks to all relevant textual data - Hebrew and versional - such that in situ comparison of analyzed texts would be no more than a click away.
