When tile starts to get out in the 10mm range, particularly in higher
grades of tile, scoring and snapping will require a very good tool,
not the el cheapo at the home store.

And still, there will be a certain minimum learning curve.

Most pros will be using a wet
saw.

"Pros" use nothing but a wet saw (and snips), notwithstanding those
many if not most who might be paid to install tile.

If scoring glazed tile doesn't chip the glaze, it risks it, and
unglazed edges can be hit or miss too, usually miss. Even a cheap
saw, per Red (or rented), is better than scoring, and a homeowner
probably shouldn't try any significant snipping... unless their tile
is cheap and/or they've got plenty extra.
