according to this, soapui wins for two main reasons:
- from the article: A big difference from the SoapUI here is that you should have SOAP requests already to be supplied to JMeter, where as in SoapUI you can generate them.
this is a big deal in fact..
- again from the article: The learning curve of SoapUI is shorter then the JMeter, mostly because SoapUI automates a lot of tasks related to the creation of the Web services test plans.
we are in a hurry, so shorter learning curve is attractive..
