It's knowing how to "tweak" the fit that makes the difference.
Another thing to keep in mind is that adding glue to the joint can make a big difference. Glue causes the wood fibers to swell slightly. So a joint that fits very snug when tested "dry" can end up being impossible to fit together once you have glue on the pins and tails.
TOO 100SE. On the other hand, you want to avoid a joint in which the tails slide over the pins without any persuasion at all. If this is the case, you may end up with a weak joint and visible gaps between the pins and tails. And a sloppy joint will lose some of its built-in "locking" effect.
