I've always used the electric toothbrush from Oral B and still in use with the standard Rotating round brush. Now I have ordered the TriZone because she was an Amazon Lightning supply and in about the cost, what cost the "normal" round brushes. The feeling is different, and I would like to stress that this is neither better nor worse, just different. The cleaning result is in my opinion comparable to what is for me, I would not spend more on such a brush. Positive is perhaps that one attentive brushing again, just because the feeling is different. Another positive aspect is that all the brushes fit all toothbrushes and can vary therefore times. On the downside, the new brushes are much more expensive, which in my opinion is not justified.
