Biscuits offer no strength in a joint and only help with lining things up and keeping them in place while the glue dries.
Although dominos offer strength, they are after all just oval dowels, I’m guessing https://www.dm-tools.co.uk/Festool-576427-240V-Domino-XL-DF-700-EQ-PLUS-Jointer-and-DS-XL-D12-D14-Domino-Assortment/P12810 ££££!!!! is enough reason to just use a router.

The domino is well worth it as a professional tool. It's one of those tools that most amateurs lust after but the price is enough to make it hard to justify.
Very handy tool to have though. Incredible joint strength and you can assemble and break down as much as you like. I use them with Rafix to make big pieces of furniture that have to be sprayed and delivered in much smaller chunks.

Is this so? My understanding was that they are both ways of simplifying loose tenon joinery (and within that, that dominoes are geometrically superior due to width, snugness of fit etc but that they are essentially using variations of the same mechanics to join?)
(Not being snippy - hoping to be set straight by someone with more knowledge than me if I’m miseducated!)
