Image handling in pyqtgraph is much more complete (again, no ROI widgets in qwt). Also, pyqtgraph is written in pure python, so it is more portable than pyqwt, which often lags behind pyqt in development (I originally used pyqwt, but decided it was too much trouble to rely on it as a dependency in my projects).
