I have several poems that I enjoy, but if you're talking poets in general: Robert Frost, William Butler Yeats, T. S. Eliot, W. H. Auden, Edgar Allan Poe, and though his poetry could be absolutely wretched, H. P. Lovecraft. (see the Fungi From Yuggoth collection).
I also have a number of poems that I just adore:
Kubla Khan (Samuel Taylor Coleridge)
Atlantis (W. H. Auden)
The Eagle and the Mole (Elinor Wylie)
Ulalume (Edgar Allan Poe)
These are just a very small sample.
As you can tell, my favorite poetry also tells about my personal poetry style. None of my poems have ever had the word "I" in them as I believe the general preference is for poems that tell a story yet, at the same time, make the reader think.
(This is my personal opinion. Actual mileage may vary. ;-D
