In a crux, it depends upon your application for which you are using the data file. The TSV file format is a more constructive and a more technically sound format. Whereas CSV is more prevalent and is being used more than its counterpart. Also, handling delimiters becomes easy in case of using a TSV file. So it is evident that TSV file is the better version of a CSV file but it is the CSV file that is winning the popularity battle here.
