I have used Sonicare and the Braun Oral-B, luckily I work in the dental field and got a discount. I personally like the Sonicare the best because it just seems to clean better. It uses ultrasonic waves to blast debri off teeth and while it doesn't replace flossing, can even help a little between teeth. The Oral-b is perfectly fine if cost is an issue. It uses a pulsating(in/out)motion coupled with a rotating motion and works well. Either way you will see a difference in how your mouth feels compared to using a manual brush. Another thing to consider, if you are extremely sensitive, the sonicare can be very "ticklish" until you get used to it. If money was no oblect, I would buy an sonicare. If you want a good affordable electric toothbrush, go with the oral-B.
