I have been watching Star news for quite sometime on continous basis. I found it best compared to other news channel. The best program I found so far is everydays Newshour at 10 pm. It gives you complete day stories ranging from Politics, Sports, Bollywood etc. And the best part they invite people from all the concerned parties in the studio and try to get into the depth of the topic. It is at best when Rajdeep Sardesai and his companion debates with personalities.
Also other programs like Big Fight is worth watching. Apart from this the morning Breakfast News is also good as they cover the main headlines and stories quickly and you dont see too many ads in the break. Atleast this 30 minutes gives you an insight of all the things happened overnight.
The host are definately above average especially of English News. One more thing: If you also look at the advertisements during the breaks it is of better quality compared to the ads in other news channel.
Though Aaj Tak goes into detail of the major stories, sometime you tend to be restless and found boring.
Other channels are Zee News and Jain TV which are not worth mentioning.
