Best for mostJames E. Falen · 1990
James Falen's Oxford translation is the one I'd start with — it reproduces Pushkin's tricky 'Onegin stanza' in colloquial, sparkling English that actually reads like the witty poem it is. Hofstadter's favorite, and most readers'. This is where I'd start.
Most literalVladimir Nabokov · 1964
Nabokov's is the famous anti-translation: he threw out rhyme and meter to render Pushkin's exact sense, across two volumes with a vast commentary. Deliberately 'ugly,' and indispensable as a crib — not the one to read for pleasure.
