Depends on if you like the result...

Yes.

Early versions had quite severe side effects. Later the
overlap factor of the block processing was increased, this
more or less hides the artefacts, but they are still there.

Another thing to take into account that at LF the real 
filter does not correspond at all to the one shown in 
the GUI.

If you want one that has this type of 'graphical' filter
I suspect the answer is no. But you don't need graphical
filters for mastering, a multiband parametric will give
better results.
