Thank you for all the comments.  I have decided to go with GPT mount.

I rerun size checks and was not able to reproduce the difference 
reported previously with or without df -H option.  So, it appears to be 
my bad.  here is a short log:

% sudo mount /dev/ufs/back /backup/
% df /backup/
Filesystem    1K-blocks    Used    Avail Capacity  Mounted on
/dev/ufs/back  50778204 2403432 44312516     5%    /backup
% du /backup/
2403432    /backup/

% sudo umount /backup/

% sudo mount /dev/gpt/dback /backup
  % df /backup/
Filesystem     1K-blocks    Used    Avail Capacity  Mounted on
/dev/gpt/dback  50778204 2403432 44312516     5%    /backup
% du /backup/
2403432    /backup/
