I'm okay with people RPing their paladins as Lawful Good types mainly because there's not really a huge wealth of information in game on exactly how the Sultansworn act other than that they protect the Sultanate and were a whole lot better as an organisation back before the Oathkeeper went 'poof'.Â
Once you take that aspect of them away, all you really have is the way SE presents the two main NPCs (not the ones simply bribed by the Montarists as if we're going with uncorrupted Sultansworn, they'd be more loyal to the Sultana) in the Paladin quest behaved, and both of them pretty much fall in line with the "Lawful Good" code-of-honour type paladins.
That said, I saw them as Knight-Errant-types as well and I think there's plenty of flexibility to be a paladin that is not a cut and dry DnD stereotype.
