I had the Jeckle hyde pedal, which I am thinking on the Jeckle side it was their route 66??? If so, I thought it was a great sound, worked very well for me. I can't compare it to the ones you mentioned however. I didn't use it to really boost a distorted amp, but give a nice breakup on a clean channel.
love the route 66 into a clean amp for slightly overdriven tones - especially with a hint of compression. But, I've not dug any of the Visual Sounds pedals for boosting.
