I am looking for input about the "best" .NET Profiling tool(s) for both performance profiling (i.e. perf tuning, bottleneck detection, etc.) and memory profiling (i.e. leak detection, footprint analysis and optimization, etc.).
Specifically, which of the following (listed in no particular order) profiling tools (and which edition, if applicable) would you recommend, and why?
A1: Microsoft's CLR Profiler (free)
A2: Microsoft's Visual Studio Team System's Profiler
A3: AutomatedQA's AQtime
A4. Compuware's DevPartner Studio
A5: Jet Brain's dotTrace
A6: Red Gate's ANTS Profiler
A7: Other?
The recomended tool(s) _don't_ need to be free, but I'm specifically looking for recommendations (and/or warnings to avoid specific apps) based on personal experiences and/or evaluations (rather than just a link to the tool's website). Also, the cost of non-free tools needs to be justifiable based on a positive ROI (preferably near term) in comparison with cheaper or free alternatives.
Input from anyone who has personal experience with more than one of the above tools and that compare and contrast the recommended tool(s) with the tools' competitors would be especially appreciated.
Thanks.
