I have bought this bike a month ago after lot of analysis and juggling through all other bikes in 150cc segment. Actually it depends on your priority. My priority was to get a fuel efficient bike along with some styling and riding comfort. and CB trigger is the perfect combination of these things. About other bikes, these were the cons which let me choose this bike over others.
Apache- Bad avg and bad riding comfort.
FZ- worst mileage in this segment.
Hunk/CBZ - There was nothing much wrong with these bike but I already own hunk so I discarded this option, otherwise, Hunk is a tough competitor to CB Trigger
SZ- moped type looks
pulsar - bad engine quality, low quality parts, high on maintenance, after two years, engine will start barking like a mad dog.
unicorn- looks like a 100cc bike. No styling at all.
