I don't think we need a full blown Church of HC-110, but a designated feast-day would be nice.
When shooting Delta-100, I personally think I get better shadows with XTol-1:1, but there is certainly nothing wrong with HC-110. Works well with Tri-X, and certainly behaved more than adequately with Agfapan 100 in sheets. Primary advantage is that it's virtually unkillable, and can be mixed in small batches from concentrate, though I preferred to make up a liter or so at a time, rather than deal with syringes.
On the other hand, now my local store stocks XTol, D76, and D19, and doesn't HC-110, so that does cut the decision-makingn process down somewhat.
