I prefer to show DEPTH COMPLETED, plus the number of root moves searched at the
next depth.  I think that depth completed is a pretty universal thing.  Alot of
programs don't show how much has been done at the next search depth, partly
because this can be complicated by re-searches etc.

In general, I think it would be great to agree on a standard format and a
standard set of information to be presented.
