We went to Rigi and Pilatus last year. Of the two, we liked Pilatus better. Better facilities at the top (hotel, restaurant, large deck terrace, gift shop, etc.). I can't comment on the relative views since we rode through a heavy cloud cover that covered the middle half of each mountain on the way up, so what we could see once we got to the top was a sea of clouds in both locations with multiple mountaintops peaking through. Which in fact was pretty scenic in its own right.
One nice thing about going to Rigi is you can hop a boat from Luzern, and enjoy a scenic ride on the way. We returned to Luzern by taking the cogwheel train down to Arth Goldau & catching another train back to Luzern (quicker).
For Pilatus, it is a 20 minute train ride to the base at Alpnachstad from Luzern. I would not recommend taking the boat back from Alpnachstad, its one hour at best via boat.
