Which replication to use?

Hi,

We need to get data from various sources to SAP Hana.

Seems we have 2 options:

1) use SAP HANA Direct Extractor  which is also able to work with SAP versions lower than 7.0;

2) use Trigger-Based Data Replication with LTR  which can handle both SAP and non-SAP source systems.

Per your experience,  what other factors we should take into consideration before decide which replication method to be used?

Thanks!
