“SQL command” vs “Table or view” when importing entire tables
At one point in the product's past, selecting the table name from the drop down versus writing an explicit SELECT * FROM MyTable resulted in one fewer operation being performed. The table name selection did...something I can't reproduce now. It'd issue a command like though that resulted in a SELECT * but with an outer wrapper around it.

Profiler reports for 2014, it issued the command select * from [SB].[EventLog] A 2005/2008 instance would have indicated it did something like sp_somethingweird [SB].[EventLog]
