They are definitely, without a question, much more effective at cleaning your teeth. My guess is coincidence vs. you had a poor technique when it came to using them
i noticed the offbrand ones claiming very high rpm, are likely not true, or just oscillates. also sonic and rotating are somewhat different too. some off-brand sonic ones are good too, epsecially the ones where you can set the intensity.
