I'll use a snap, and I'll use a swivel, but never a snap swivel.  One part of the combination is usually weak. A duo lock snap, tied with a Palomar is great for cranks. You can remove the split ring connection, if you are committed to the snaps. Swivels are great for lures that randomly twist, like spoons or inline spinnerbaits.  I use a split ring and then a swivel.  You can tie direct to the swivel, or use a duo lock snap, if you want to make quick changes.

The disadvantage of the snap is -----> you

 

Why you ? people look at snap as a quick way to swap lures  but that has a dark side if you do it the wrong way and the wrong way is when  you don´t bother to check your line on a regular basis looking for signs of wear in order to cut and retie as needed.
