title: IsNothing versus Is Nothing
body: <p>Does anyone here use VB.NET and have a strong preference for or against using <code>IsNothing</code> as opposed to <code>Is Nothing</code> (for example, <code>If IsNothing(anObject)</code> or <code>If anObject Is Nothing...</code>)?  If so, why?</p>
  
  <p>EDIT: If you think they're both equally acceptable, do you think it's best to pick one and stick with it, or is it OK to mix them?</p>
