All the bikes you mentioned are great to ride, built for the city (commuters). They are almost in the same price range and category (single cylinder, chain driven). Companies have put in an equal amount effort to make their product successful so just have fun with whatever you buy.
The problem occurs for bikers who are stretching their budgets too far to get a Harley Davidson / Triumph or a BMW Motorcycle. There are far too many factors, variables to consider and the risk is high since that is their life savings.
We want a fun practical motorcycle to commute every day. Buy what your heart desires and have fun.
