Having visited all three (some multiple times), my personal favorite is the Schilthorn. The views are simply stunning, I find the views much more compelling than those from the Jungfrau. There is a revolving restaurant at the peak that enables you to get a 360 degree panorama (one rotation per hour)
The really special thing about the Jungfrau is the miracle of the train that takes you there. If you are a train person, by all means go!
The Matterhorn is special, of course, but personally I wouldn't make the trip just to go see it.
In all cases, please be aware that your ability to see anything from any of these peaks (or even to see the peaks from the ground below) is entirely dependent on the weather. You cannot "schedule in" a visit to any of these peaks any more than you can schedule the weather. You can only make plans and hope for the best.
My recommendation is to go to Murren and spend both Saturday and Sunday in the area. That way you have a better chance of weather cooperating on one of the days. Also, clouds often come in during the afternoon so you should plan to stow your bags and immediately take the lift up to the Schilthorn if you can go up on Saturday. The Bernese Oberland is, in my opinion, the most beautiful spot in all of Switzerland. It would be a shame for you to come all the way from Geneva to only spend one day there. Let us know if you'd like additional ideas of things to do. I stayed there for three months one summer and never got bored.
