How can there be a favourite poem? Milton, Dickenson, Browning, cummings, Arnold, Shelley, Frost, Donne, Eliot, Wordsworth, Shakespeare, Plath, Thomas, Pope, Whitman, Blake, Ginsberg, Chaucer, Hopkins, Neruda, Williams, Spenser, Angelou, Byron, Pound, Coleridge, Roetke, Hildegard of Bingen...

There are favoured poems, favourite poets, perhaps, but they are legion.

The process of poetry is what engages me - and without any claim to inclusion in the league(s) of those above, the only process I know about is my own.
