Visually neater is not really a good parameter to judge.
And in a class you can also overload __getattr__ to get the same
syntax as a dictionary.
But (>100) parameters seems really a lot, are you sure you can't split
in many classes instead?

Classes have also the advantage that you can do many things behind the
scenes, while with plain dictionaries you can't do much...
Where do you take those parameters from and what are they used for?
