From what I've read, you should run something like REW to verify the outcome. You may end up with better or worse results than setting the subs up manually using tools like REW. I wouldn't assume it's going to be better just because is done automatically.
For home theatre, I run Anthem ARC, but don't really care what happens with auto correction. Personally, for music, I don't see the benefit because I'd use REW anyway.
