I am a beginner to Handel myself, so I am only able to tell you what works I have. But first I think it would be helpful for us to know why you don't want Messiah recommendations. If it is the religious aspect of the work you don't like, then we can recommend Handel's secular works. If it is the large-scale oratory aspect of Messiah you don't like, then we can recommend other types of works. If it is simply that you already have a recording of Messiah, then I suppose it doesn't matter.
My Handel collection (excluding Messiah) is as follows:
Concerti Grossi, Op. 6 (Andrew Manze; Academy Of Ancient Music)
Judas Maccabaeus (Robert King; The King's Consort; Choir of New College Oxford)
Judas Maccabaeus is a large-scale religious oratory, so it may not be to your liking if you do not like Messiah.
