lol no. Revan and the Exile's "character" is pretty much entirely determined by the player in the two KotOR games.
The only thing that can be argued are the attributes of the characters that remain constant irrespective of gameplay, and of course, how you view those is up to you. For me, the Exile is less of a Mary Sue and has a more unique origin; she isn't a character designed to be godlike but rather just a Jedi who managed to live without the Force. All the "Wound in the Force" stuff is a bit excessive, but being a unique Jedi with some distinct talents is somewhat more appealing to me than someone who simply and naturally excels at everything. She isn't a universally-recognized badass, nor is she an all-in-one character (I realise that both factors may make Revan more appealing to some, especially the second), just a unique survivor.\
I love Revan as well, of course, and the two factors I mentioned above are part of that, but in the end, he's just a prodigius maximus that you can insert into quite a few different universes and still work. The Exile is not only unique in Star Wars but is also a distinctly SW character; she wouldn't be able to function as she is in another universe. I also like the nature of her greyness more than Revan's; Revan is really just black and white mixed together, whereas the Exile has a shade of inherent greyness in her character that's absent from most characters, including Revan.
And let's face it, Meetra Surik and Revan had virtually no character in either Revan or The Old Republic, both of which were horribly written. So we can safely exclude those.
