The wet saw is more versatile and will make more cuts than the score and snap. With the score and break you can only cut straight lines pretty much. A wet saw will allow L’s and even curved cuts with proper technique. The wet saw will also give you a nice smooth edge on the cut. One of the biggest drawbacks is the cost and they are messy!

If all you’ll need to cut is straight lines then the score and snap is the way to go. You’ll have to file the edges to smooth, but not a big deal. I’d suggest looking at the cuts you need to make and determining the cost vs. the use. You can buy a carbide hole cutter and coping saw blade for a lot less than a wet saw.
