You are right, they are alike.

Kyo and Ichigo are archetypal personality types that can be found in fiction (not just anime and/or manga) world wide. If you looked beyond these two characters you'd find that most of the other characters will match with a counterpart in the other series. Often the story and genre will be defined by where the character emphasis is placed. In Bleach the emphasis is placed on the avenging hero archetype (Ichigo) which makes the a show an action/adventure. In Fruits Basket the emphasis is placed on the caring/understanding character (Tohru Honda) making this show a romantic comedy. If you compare the two shows you'll see that Tohru's counterpart is Inoue Orihime in Bleach. Same types but different empasis.
