Man, you’re pretty defensive about your toothbrush. Seriously, lashing out and making tacit accusations of dental problems and lack of dental hygine because other people do things differently? That’s weirdly aggressive and borderline “that guy”, lashing out like that over something as mundane as a toothbrush.
Like I said - or more accurately, relayed - both do the core job fine, just that one does the same job better, with more useful features. If you can upgrade, you should, but that doesn’t mean that if you can’t(or I guess just don’t want to) that it’s bad. One is a 4 out of 5, the other is a 5 out of 5 - it’s cool either way, it’s fine.
