I only use two official supplements, but I think that both of them are great and, thus, deserve a mention:

1. Unearthed Arcana
2. The Spell Compendium

 

[theemrys]

1. PHBII
2. PHBII
3. PHBII
4. Spell Compendium
5. Complete Scoundrel
6. Libris Mortis
7. Complete Adventurer
8. Magic Item Compendium
9 Unearthed Arcana
10. Complete Mage

1) Unearthed Arcana - most read and least-used book in our games, it seems
2) PHB II - I think three out of five PCs in our group use this one.
3) Complete Scoundrel - Spellthief support? I'm there.
4) Complete Adventurer - Love me my spelltheives.
5) Complete Mage - Too cool. Too cool.
6) Monster Manual III - the most commonly used monster book that isn't MM I.
7) Dragon Magic - Just like it.
8) Spell Compendium - It gets used by a few players, from time to time.
9) Complete Warrior - best PrCs in the complete series.
10) Heroes of Horror - just a fun read.

 

[jrients]

1) Tome of Battle: Book of 9 Swords
2) PHB II
3) Unaerthed Arcana
4) Spell Compendium

I can't make it to 10, because most of their products suck, but I do have one:

Don't threadcrap, please. Seriously; there's no real benefit to that preface other than causing arguments and derailing the thread. That's not a great reason to post in a positive thread.
