But since you posted this in the SilkTest forum, I guess your answer is SilkTest
Otherwise, maybe you really meant to post your question in the General or Automated Testing forum.
My final answer: Evaluate each one of these test tools and see which one best fit your needs. Find out which one works very well with your application(s). All the tools you mentioned are supposed to be very popular and are all good. Good luck and take your time evaluating and picking your "better" tool.

Kind of application, web based, windows and Unix
Expertise and experience of testers - good programmers or not.
Level of automation needed.
I have worked with all these three tools and recommended these three for different application. Feel free to send an email to email@example.com for any assistance in this matter.
I think, the comparison document which I have attached gives a clear picture about the usage of various testing tools for various type of applications. For different functionalities there is a trade off.
