My experience is similar; often not worth the extra travel time, and often times, expense.
A rare exception might be DUB to ??? and back into LHR, but this often depends on the cost of the LHR-DUB fare. As I typically drive to the airport (save quite a bit thanks to parkatmyhouse.com), I need to depart/return to the same LON airport.
