I'm getting into building various hobby projects using
microcontrollers (specifically, the Pic32) and need something to help
me debug the hardware.

Am I better off getting a USB mixed-signal scope, such as this one:http://www.bitscope.com/product/BS442/

or getting a more traditional digital storage scope, such as the
Tektronix TDS2014B?:http://www.radarinc.com/cgi-bin/wspl.sh/prodinfo.p?itemnum=TDS2014B

The Tektronix scope is MUCH better than the Bitscope, but it depends
upon your exact requirements and budget as to which one is best for
you.

The Bitscope is only 40MS/s, that gives an effective single shot
bandwidth of around 4MHz (don't get fooled by the 100MHz analog
bandwidth figure, you can't capture a single shot 100MHz signal with
this). But the bitscope has 128KB of memory, the Tek only has 2.5KB,
but the Tek is 1GS/s.

There are fairly cheap name brand mixed signal bench scopes available
which are well worth looking at. e.g.: Rigol:
