One man's opinion...
I have a BR-1600 recorder and discovered when you use several inputs at once, you can't use the internal guitar sounds. I already had the SansAmp, but I ended up getting a V-Amp 2 for when buddies come over to jam. Generally, I've been plugging in the Behrenger, and my buddies use the Sansamp. Although I really like many of the tones you can pull from the V-Amp (with patience), I'm constantly amazed at how organic sounding the SansAmp is during playback. It just sits so nicely in any mix we do.
It may not have bells and whistles up the wazoo, but it sounds killer.
Distortion is such a personal thing, though. I suggest you plop down in a music store that carries the both of them.
Hope this helps.
