It's not as good as "worse-than-most" but both make me titter.
To be honest, the last time I saw KN was in Berlin in 2004 and I fell asleep (In Beethoven 5). I enjoyed a Mahler 9 of his at the Barbican many years ago, and his Mahler 3 on Teldec was excellent (Or was it Erato?).
Not sure if I've ever had the pleasure of seeing FWM --- I think I might have seen a Beethoven/Bruckner 1 pairing at the RFH many years ago, but my memory isn't accurate any more when it comes to concerts seen, aside from those really great ones though.
