WHICH IS THE BEST SHARE BROKER

I am planning to open a trading account with a reputed share broker ..

Can anyone guide from their personal experience as to who is the best share broker in terms of services and facilities ?

I  have selected a few options : -

1. SHAREKHAN

2. ANGEL BROKING

3. INDIAINFOLINE

4. MOTILAL OSWAL

It would be of a great help to me ... as I plan to invest in share market . I m reading a lot of books on that . 

THANKS IN ADVANCE
