I like Yeats well enough, but not more than I like Eliot at his best. In fact, I think Frost is better than Yeats - and at least as "modernist".
Also, this seems odd: "... Yeats could be personally unappealing, even arrogant and intolerant, although not more so than Eliot and less so than Pound." I suppose Eliot could be arrogant, but his intolerance - and possible bigotry - pales beside Pound's outrageous anti-Semitism.
