I fly a couple of F9 flights a year for one reason: they are often significantly cheaper than any other airline on that route. If that means I get to take a trip I wouldn't otherwise then yes, they are worth it.
However, I had a miserable experience on a redeye in their new slimline seats which means I won't fly them overnight again. But for day flights...without hesitation.
