Faure is the hidden glory of piano repertoire, I've warmed up to Stott with time actually. After constant listening, I find Naoumoff very generous in the nocturnes, please give that a try, his tempos are slower which I prefer, I personally can't stand the hurried tempos of eric la sage.
Delphine Barin does good barcarolles, maybe not the best at times but I return to it. Lortie has put great effort into recordings as well which I'm often happy with.
As I understand it faster and detached playing is stylistically more appropriate for Faure but I feel that way occasionally with his music not always.
That's my experience, being a pianist that has played quite some Faure in the past year, I'm always eager to learn more. Hope it helps. A couple names listed above might point me in new directions, glad to see them as they are new to me. Also try Pennetier, his fairly recent recording is in the 4 disc album range which is just about complete, I refer to it occasionally.
