There is some overlap between the domino and biscuits but there are some differences as well. Biscuits don’t make good alternatives to mortise and tenons where dominos do. It probably is closer to dowels in comparison but it’s a lot faster to setup and use. I don’t own one but i did borrow one for a project I was working on and it worked really well. It’s fast and easy to use which as others have said is key for production work. I can’t think of a faster way to make loose mortise and tenons honestly. If I was making pieces for resale I would own one no questions asked. As a hobbyist it’s a harder call to make.
