Your fingering is not necessarily more or less "correct", but you will get a slightly different sound.  The suggested fingering will have a more even delineation of the notes, while your fingering will add a little variation in the shaping of the phrase.

So,it's a matter of musical interpretation.  If you are changing the fingering because you prefer the way it shapes the phrase, then that's great.  If you are changing the fingering to make it easier to play, that's usually okay, but just be advised that it will slightly change the sound you produce.
