One reason not to choose logical standby would be if you often perform massive inserts/updates/deletes in the primary database. I have verified a performance issue in 10.1.0.3, 10.1.0.5 and 10.2.0.2 where SQL Apply steadily gets slower and slower while processing a large number of changes that are part of a single transaction. A workaround is to do commits every 100,000 rows or so but that would add complication to your code, no doubt.
