But, why? in my opinion "rather than" are right, but, don't forget that is just my opinion. I wait for your opinion.

It looks like there was some discussion which has now been erased, but I believe that it should be "I prefer bananas to apples." This page indicates the same:

In speech, "I prefer bananas rather than apples" would be fine, but in writing, it looks a little odd, since "prefer" already carries the "rather than" meaning.

It should be either of the following, whichever matches.

I prefer bananas to apples.

I'd rather eat a banana than an apple.
