I've had no issues with eBay, despite the fee increase. I list my stuff at reasonable prices, generally under cutting recent sold-for prices and still make a few bucks.
It depends a lot on _why_ you are selling your used things. I am not trying to make a ton of money on them, just trying to keep stuff out of landfills and get it into the hands of people that can use it, maybe recoup some of my initial costs while at it.
I've had okay luck with FB Marketplace, but the amount of scammers and bots on there makes it an annoying last resort for me.
