I know nothing about these tools but I do know if you're looking for a tool to be a "one size fits all" answer to any mobile device testing then you are falling short of the proper test coverage needed to be done.
Please see other mobile application threads about how to test overall mobile applications for suggestions on solid overall coverage. Mobile testing requires strong critical thinking skills and one tool will not be a good application.
However, the merits of these tools to be discussed would be a fantastic addition to this forum. Please offer your experiences with regards to software testing.
