Judging by this and your other recent thread
about the Kona Dew Plus I'd say you're in a quandary about which bike to buy. I could offer my opinions based on links that you provide to this or that bike, but IMHO you would be better served by giving us a list of criteria that you would like your dream bike to have. So far I've gleaned that you want a "performance hybrid" type of bike with disc brakes, and the ability to switch between a traditional derailleur drivetrain and an IGH. Please correct me if I'm wrong. I don't know your budget, but assuming by the examples you've provided you're looking in the $500-$800 range. Again, correct if I'm wrong.
If money were no object I would suggest buying a frameset (like something from Surly or Soma) with semi/full horizontal dropouts or an eccentric BB, then building two rear wheels; one with a freehub and cassette and one with an IGH. Either that, or just buy two bikes. To stay within your budget, however, you might want to consider going used.
I had similar set of criteria before settling on my latest bike and believe me, making major mechanical modifications on a bike can be a pretty pricey proposition. After calculating the cost of modifying my Schwinn to an IGH drivetrain and from rim to disc brakes, and also the cost of buying a used bike and building it to my liking, I figured I would be better off just buying a bike with the features I wanted. So... I saved my pennies and I now have my belt-driven/IGH'd/disc-braked Norco Ceres, plus I got to keep my Schwinn for backup.
Good luck with your search!
