I would suggest go with the pass. It will be more economical and also make your mobility easier. You can always skip the attractions which you don't want see, but it gives a good feel of the city and spend as much time at the attractions of your interest.
Hi Nikhil, getting a pass is a better option, it would be cheaper and you can decide amongst what you want to see and what you want to miss. I have attached with this message few trips, that can help you plan your trip
