There's no better complete set, in my opinion, than the Boult.  However,
there have been better recordings of individual symphonies, although not
recent recordings.  Barbirolli's Fifth and Second I prefer to Boult's.  I
think Haitink's Seventh edges out Boult's.  The Fourth has been blazingly
recorded by Mitropoulos and by the composer himself, although these are
hardly the last word in sound.  I find the Thomson set dull and at times
clueless.  I think the Hickox CDs good, but at best no better than Boult.
Bernstein recorded a disappointing Fourth, just in case you might be
tempted by the conductor's star power.
