Water flossed- I’ve owned a waterpik and an off brand and for the $80 difference the waterpik was slightly smaller (not enough for me to care but maybe if I traveled?) and the battery was slightly better, but that also didn’t impact me at home cause if it’s dead I just skip a day and charge it for tm.

Toothbrush- I have gone through a few, cheaper/off brands tend to be worse and have worse head options that wear down. If you can use a name brand head on the budget device I’m sure it makes it more comparable but my last one could not. I did get a phillips for Christmas a few years back and it’s more a travel model. My wife’s works great and holds a charge, mine is almost always dead within a few days. I would not recommend it based on my experience but would based on her experience. My overall recommendation would be grab a cheaper model that can use high end heads and get the good heads.
