<p>I was wondering; which logging libraries for Delphi do you prefer?</p>

<ul>
<li><a href="http://www.raize.com/devtools/codesite/" rel="noreferrer">CodeSite</a></li>
<li><a href="http://www.gurock.com/products/smartinspect/" rel="noreferrer">SmartInspect</a></li>
<li><a href="http://log4delphi.sourceforge.net/" rel="noreferrer">Log4Delphi</a></li>
<li><a href="http://tracetool.sourceforge.net/" rel="noreferrer">TraceFormat</a></li>
</ul>

<p>Please try to add a reasoning why you prefer one over the other if you've used more than one.</p>

<p>I'll add suggestions to this question to keep things readable.</p>
