Avid Juicy 5's are amazing. Running one on my trials bike at the moment. I hate proper bitey brakes, so this brake is perfect, plenty of hold and modulation.  Also Magura Louise are amazing brakes too. I had the 180 and it was SOOOOO powerful. Gay boy Kennard has it now, I think he loves it.  For a streety bike I would go for the Avid over the Magura.
