Business One Way Indirect or Return Economy Direct

[turneip]

What is better?

We can either fly business class one way direct (BA Club Suite), then return indirect in economy (with Emirates) or we can fly direct economy return (Eva Air).

We get lounge access so we could get off at Dubai and shower and have some food etc.

Business, definitely.

How long are the journeys? And how long is the layover if you go indirect?

Direct both ways. Would not bother with indirect flights as those just make a long day even longer.
