Does anyone have an opinion or thoughts on the Two Brothers Jucebox controler vs Power Comander. I have added two brothers cans and filter and would like complete the package.

 
I would think that with the multitude of people running either PC3 or PC5 you would be better off going that route, not too mention most Dyno tuners are experienced with them, there is nothing special about their exhaust that would warrant a special fuel controller, its just outbound flow. Plus you would have a much broader resource for maps with a Power Commander.

I don't understand the programing for each one. It seems they accomplish the same results with different programs. Which is better for everyday riding?

 
Which is better for everyday riding?
Whichever one you can get tuned to your liking.

Looks like the Juice Box Pro is fully customizable like a Power Commander, but can tuning shops work with these as easily as Power Commanders? If they offer a pre-loaded map that was tuned for the same configuration of your bike, then it will probably make you happy. However, there's not just one way to tune a bike. It is tuned with specific goals in mind (max power/smoothness? maybe compromised for some better fuel economy while cruising?). You might want to try to find out what they aimed to achieve with their supplied maps before you buy one. With the Power Commander, there are already several custom maps floating around tuned for different variations of modifications and goals (the smoothness map, for example, sacrifices a bit of fuel economy for very smooth throttle response). No matter what device you use, just always be sure that any map you use was tuned for a bike that very closely matches the configuration of your bike (difference in after market slip-on brand is probably fine, but difference between stock and after market would not be good).

Don't fall for marketing about how you can easily just push some buttons to adjust the fuel levels to your liking, and how it can be done without the "hassle" of hooking up to a computer or expensive professional tuning. If you don't have the proper tools (exhaust analyzer, etc.) and knowledge, then you're just shooting in the dark and getting a placebo effect that you made a change for the better, when you may have actually made things worse. You can't tune fuel injection by "feel". You need actual measurements of air/fuel ration and knowledge of which areas of throttle/RPM combinations are used for various purposes (steady cruising, light acceleration, heavy acceleration, etc) to make informed decisions on whether to increase or decrease fuel in a particular area.

If you really want to play around with tweaking your fuel map to get the perfect balance of smoothness and fuel economy for your style of riding, then you should get a system that uses a wide band O2 sensor and self-adjusts to match specified air/fuel ratios. You really need data logging to be able to pinpoint which areas you want to adjust, but once you identify which areas of the map are used most for cruising, etc., you can safely make adjustments in terms of air/fuel ratio, which is much safer and more predictable than unitless adjustments to the amount of fuel. Check out the PCV + AutoTune or the Motty AFR Tuner if this sorta thing interests you.

 
Just noticed this:

"Software is compatible with Power Commander, so you can download Power Commander maps to the Juice Box Pro"
