My very favourite analogue Sibelius symphony recording is Symphony #2 by von Karajan conducting the Philharmonia Orchestra on EMI, recorded in 1960.
Of course, if you were to ask about digital recordings, there are many to consider as well--including the splendid complete Sibelius symphony cycle by Sir Colin Davis conducting the LSO on RCA, now available in an inexpensive 7 CD box set put out by Sony Music.
