I'm having a lot of fun with Velocity right now. It has a distinct advantage
over JSP in one area for me: it'll run outside of a Servlet Container
easily, and very nicely thank you.
As far as mixing presentation logic and business logic together, well, you
can do that with Velocity, too. Although it makes you think longer and
harder about it. Here's a recent template snippet I wrote. This is something
you wouldn't necessarily be proud of doing with Velocity.
----8<----
#foreach( $event in $events )
$yapper = $meeting.getParticipation( ((MeetingEvent)$event).getFromId() )
#if( $repRole.equals($yapper.getRole() )
$repId = $yapper.getParticipantId()
<font color="$black"><b>$yapper.getName()</b></font>
#else
<font color="$blue"><b>$yapper.getName()</b></font>
#end
#if ( $event.getClass().getName().equals($chatEventType) )
((com.webhelp.emeeting.events.ChatEvent)$event).getStoredData() <br>
#else if( $event.getClass().getName().equals($urlPushedEventType) )
<a
href="((com.webhelp.emeeting.events.URLPushedEvent)$event).getStoredData()">((com.webhelp.emeeting.events.URLPushedEvent)$event).getStoredData()</a><br>
#end
#end

Although I think I can clean this up a lot using #macro, it shows how you
can use the dark side of the force even with a great tool like Velocity.
