I think it just an alternative of UI, one is based on C++, another is  
based  
on Python. But in the future WX one will be removed from GR so you may  
want  
to get used to QT one.

They’re both implemented in C++, and both wrapped in Python. New feature  
work, however, is aimed at the QT-based blocks in GNU Radio, so you  
won’t see as many WX blocks or features.

One of the issues with the WX blocks is that the “instrumentation”  
blocks are very poor performance, and they don’t have as much of a  
“crisp, modern” look about them.

The performance issues could be fixed, the look and “clunk”, probably  
not.
