> an electric toothbrush, but I've only used one off and on
There’s a good little joke in here.
FWIW, I’ve gone back and forth on electric toothbrushes and settled on non-electric. I’ve found that a medium-firmness bristle and a rigorous and thorough brushing is what leaves me feeling cleanest. Plus it’s simple, easy to replace, and easier to properly dispose of.
Then again, maybe a super high end electric would change my mind.
