HTTP Tools for analysis and capture of requests/response

Question

I am looking for tools that can be used for debugging web applications.I have narrowed my search to the following tools:

1. HTTPwatch.
2. Fiddler.
3. ieHTTPheader
4. liveHTTPheader.

It would be great if some of you having experience with these tools could discuss their pros and cons (features that you like or you think are missing in some of the tools but present in others).I am majorly confused between HTTPWatch and Fiddler, I would prefer Fiddler (being free) if it could fullfill all or most of HTTPWatch's features (however I am ready to pay for HTTPWatch if it's worth it).

P.S. - I know HTTPWatch and Fiddler are far more powerful than the other two tools (let me know if you disagree). I am sure most of you would want more details as to what I would exactly like to do with these tools however I would like if you could compare these tools taking a broader perspective in mind comparing them as tools in general.

Here's a list of the main advantages of HttpWatch (our product) and Fiddler. Of course we're biased, but we've tried to be objective:

HttpWatch Advantages

• Shows requests that were read from the browser cache without going onto network
• Shows page level events, e.g. Render Start, DOM Load, etc
• Handles SSL traffic without certificate warnings or requiring changes to trusted root CAs
• Reduces 'observer effect' by not requiring HTTP proxy at network level
• Groups requests by page

Fiddler Advantages

• Works with almost any HTTP client not just Firefox and IE
• Can intercept traffic from clients on non-Windows platforms, e.g. mobile devices
• Requests can be intercepted and modified on the fly, e.g. change cookie value
• Supports plugins to add extra functionality
