Anyone have any thoughts on what they consider to be the best HEX
compare/edit utility?
If you're looking for an integrated solution, then your possible choices
are somewhat limited. Only few free hex editor programs support file
comparison.
A good one for this task is JHEdior:

You need a Java Runtime for this one, though. To compare files you
need to open them, first.
One of the best free hex editors is FrHed:

Load the Beta 1 of v1.1; this one has proofed stable for years.
The browsing through the list of differences after comparison
is an awful one by one approach. (Or you need to copy the list
and go to each difference by hand...)
HTH.
