best fare or best flight....

I once had a cheap KLM flight, through Amsterdam (a 24hour flight)

I prefer the direct Qatar Airways flight (preferably in Business Class)

It's a direct DOH-IAH 17h flight (10am to 5:30pm same day)
the flight back is a 15h flight (7:45pm to 7:45pm next day) ... Timezone differences make the numbers seem illogical :)
