I don't fly Southwest and wouldn't fly with them. Personally, I have seen those leather seats and I don't like leather seats. If the seat weren't leather I still wouldn't fly with them because I like to have an assigned seat. From my understanding they don't give assigned seats. Also, from my understanding-its first come first serve and that's why they have a fee. In some cities across America it probably a must or you could loose your seat, however they know in certain other cities it is almost never a situation that makes passengers loose their seat. So, in those cities Southwest could be making a bit of a mint if people are paying for this service.
