Inside the city, both the Yamaha XSR155 and the Honda NX200 will make for good companions, and it will come down to which bike's styling and riding experience you prefer. 

The XSR has a pleasing neo-retro design, and it makes a strong case for itself with its R15-sourced engine and chassis. It is also a rather fuel-efficient machine, and the only thing to look out for is that its rear suspension can feel quite stiff over bad roads. 

The NX200 - while not a proper ADV in the true sense - has that rugged look that a lot of people desire. It will also feel like the larger, more spacious machine to sit on, so if you are a taller rider, that might be of interest to you. Do bear in mind that its performance won't be as sprightly as the Yamaha's. 

A test ride of both across various road conditions will help you make up your mind. 

All the bikes you are considering are great options and have reasonable servicing costs. The CB350 H'ness is a relaxed, comfortable retro bike with a smooth, torquey engine. The Honda NX200 is a tall, quasi-ADV based on the Hornet 2.0 street bike, which means it will be suitable for daily use. 

The Gixxer and V-Strom SX from Suzuki are refined, punchy machines that are also fuel-efficient and quite reliable. 

A test ride of all 4 is in order so that you can decide which is the best option for your needs. 

The Honda NX200 is a decent option for you, considering your usage, but there are also plenty of other options worth considering before making a decision. From Honda's own fleet, you can consider the CB300F, which will offer you much better performance with similar comfort while actually costing a little less than the smaller NX200. 

The TVS Ronin also makes a good case for itself. It has a torquey, smooth engine with neutral ergonomics and great suspension comfort. At 160kg, it is also a fairly light machine. 

Take a test ride of these - and anything else you might consider - before you make up your mind.
