I have DropStuff set for full compression and ZipIt set for deflation and
whatever else it does. With just time for a few short tests this morning
before I have to go out, ZipIt sometimes produces slightly tighter
results than zipping with StuffIt Commands, sometimes the reverse is
true. The more important difference seems to be between the choice of
zipping or stuffing. I'll do some more on it tonight and send you the
results.

The very first file that came to hand for stuffing (a JPEG) after I read
this produced exactly that result. However, checking again on DropStuff's
preferences, I see there's an option not to stuff files that are already
compressed. Unchecking this has reversed the result for that particular
file.

The comparison was with DropStuff (which I'm guessing is similar to
DropZip) and StuffIt Commands. What I didn't make clear was that ZipIt
allows individual files to be added to or extracted from an archive by
drag and drop. DropStuff only stuffs in bulk and StuffIt Commands has
(obviously) to be scripted.

'It' refers to ZipIt, which I was talking about in the earlier part of
the paragraph. ZipIt only handles one format; StuffIt, as you point out,
handles several.
