Can anyone suggest which is the best PNP porgram

Best depends on many factors such as the person's background etc.

The following are some of the best PNP programs, generally speaking.

Saskatchewan Express entry program
Saskatchewan Occupation in demand program
Ontario Human Capital Priorities stream
Manitoba Skilled Worker overseas program
Nova Scotia Express entry demand program

You can also visit the cic.gc.ca to get more details. It's more official.
