Chopin etude op.25 no.1 in progress any other gd etudes to recommend?

Recently i started Beethoven's moonlight sonata and i pretty much covered the first movement...so im done with the gloomy atmosphere and went to Chopin's op.25 no.1 etude...i was thinking after i finish the etude should i finish the whole moonlight sonata or should i start a new etude?if i want to start a new etude can u give me recommendations for any lively ones?except the black key etude of course...black key arpeggios were never my strong point...
