Yes!! Handel will always be the greatest master of choruses! Here are a few of my favourites, just off the top of my head :
By Handel:
(Messiah)
O thou that tellest good tidings to Zion
For unto us a child is born
The Lord gave the word (short and sweet!)
Hallelujah (obvious)
Worthy is the Lamb and Amen (Fabulous indeed

)
-----------
Gloria Patri et Filio (Dixit Dominus)
Zadok the Priest (Coronation anthem)
Kings shall be thy nursing father (idem)
See the conqu'ring hero come (Judas Maccabeus)
From Haydn's creation :
Stimmt an die Saiten
Die Himmel erzähle die Ehre Gottes (the single best chorus in the whole oratorio!!)
Der Herr ist groß in seiner Macht
Vollendet ist das große Werk
The final chorus from Beethoven's
Fidelio and the whole last movement of the 9th symphony? That's pretty obvious though.
