I built two identical vanity bases, one with a dado and one with a biscuit joint

I mean, everyone says biscuits are fine for casework alignment, but after making both for a job last month, the dado was just better. The biscuit joint on the first one had a tiny bit of play during glue up, maybe a millimeter shift. The dado on the second one slid together perfectly straight every time. It took maybe 15 extra minutes to set up the router, but saved me from any fussing. Has anyone else found that biscuits can be a bit sloppy for something that needs to be dead square?

Totally feel you on the biscuits. Had the same slop happen on a cabinet face frame once and it drove me nuts. Dados are just way more solid for getting that perfect alignment every single time.

Read a woodworking blog that called biscuits "alignment aids, not joinery," which makes sense now.
