I finally decided on the Oral B 3D Excel. I think I have the same one you have, Princess Purr. It cost about $75 at Walmart. I decided on this one because it came with 3 brush heads (the Sonicare I was looking into only had one) and was about $30 cheaper.
I did a lot of research since I'm so neurotic, and everything I read indicated that either one would be a worthwhile investment, so the price difference made up my mind in the end.
I really like this one! My teeth feel soooooooo clean after, and I don' gag when I'm brushing my tongue. It has the 2 minute timer, but not the quadpacer thingy. It doesn't bother me though, because I have a tendency to brush my teeth for 4-5 minutes. I used this one for 7 minutes the first time because it felt so cool
