Depends what bike there off and what engine your putting them on. The end tune of engine vary massively and this defines what is the best to use. Though whatever you get your going to have to get them set for your given application. What engine are you fitting them to? Sandy or Boggy are probably your best people to talk to. Whatever you go for you will be best to use some sort of mappable injection timing as well. Carbs have a few down sides though mostly on road cars due to the MOT. Personally I would go for injection as your talking similar money and complication to do well but have and end better result.
