Hardly. The beauty of biscuit joinery is the amount of time you save, even over a plain butt joint. It makes the joint automatically self-registering, so you can just spread the glue and go. You don't even have to glue in the bisquit pockets; just slather a little on the biscuit itself. For me, it's a life saver for complicated box assemblies with a fast glue like T3 - I don't have to spend all those seconds getting everything registered.
I think the main stopper for regular guys is getting the biscuit machine.
