How do I compare two data tables in SSIS?
two Sort transformations, as Merge Join transformation needs sorted input; I guess you need to match records using ID, so this would be a sort criteria. one Merge Join transformation to connect both (left and right) data flows. one Conditional Split transformation to detect if there are correct statuses in your tables.

Here the source data flow where the OLE DB sources are merged using the primary key (PK) and FIELD_NAME as Join Keys (see Fig.2). Fig 2. The Merge Join task for verification (initial version). The joined records are analyzed in the Conditional Split task that compares the FIELD_VALUE data from both joined records (see Fig.3).
Which is more transparent SSIs or T-SQL?
The SSIS based approach is simpler and more transparent. The SSIS package is more productive in processing of large tables than the T-SQL implementation. To verify the data of different data types the dynamic T-SQL scripts should be applied consistently to each of these types.
Which is easier to debug SSIs or T SQL?
The T-SQL implementation is based on complicated dynamic SQL statements, rather difficult in development and debugging. The SSIS based approach is simpler and more transparent. The SSIS package is more productive in processing of large tables than the T-SQL implementation.
