Suggest the best broadband network available in bangalore

I live in Bangalore and need a broadband connection for home. I wont be doing much downloading, it would be more of research, social networking sites and browsing, and possibly using YouTube. After some research I came up with the following options:

Sify, Hathaway, Reliance and Tata Indicom.

Now the decision needs to be made between these options, I don't have any idea about the performance of these service providers or how good or bad they are, so this is where I require some help and advise.

Just to add the options mentioned above are given as these are the service providers available in my area.

It really does depend on where you are in Bangalor, as every area differs. But on a whole I would say Reliance and Airtel are one of the best internet service providers in Bangalore.
