The thing I find with Limesurvey is that with a knowledge of how data works in a commercial research setting and a small understanding of how to work with the API, Limesurvey can be made to do almost anything a commercial software can do.
There are some minor cosmetic issues such as keeping order of randomised lists for respondents but these are irritations to the researcher designing the survey and not a problem with the software.
I have run commercial strength surveys of 50K+ respondents quickly and easily with Limesurvey and the forum has proven to be most helpful at all times.
