Ziti vs Rigatoni
Ziti is primarily used for meat and meatless sauces. You can use Rigatoni instead of Ziti. Ziti with ridges works best instead of smooth Ziti. The material is the same, and only the shape and texture differ. Ziti are smooth in texture, while rigatoni are ridged in texture.
The basic mix is the same. So, Ziti and Rigatoni can easily substitute one another. Both pastas go very well with chunkier sauces, capturing the sauces in the hollow center and ridges.

What is Rigatoni?

Rigatoni means ridged pasta which are wide short tubes with ridges on their exterior. They are smooth on their internal surface. They are perfect for chunkier sauces as the sauce gets trapped or captured in between the ridges perfectly.
Rigatoni is around 1.8 inches in length and a width of 0.6 inches, with a thickness of the wall of 1 mm. It is somewhat wider and shorter as compared to penne and ziti. Rigatoni is somewhat curved, based on its extrusion procedure. The ridges give a furrow to the sauce.
They are tube-shaped types of pasta with different diameters and lengths. The ridges are across their length spiraling the tube. The ends are cut square and not diagonally.
Rigatoni means "lined, to furrow or to rule." They are associated with central and southern Italian cuisine. Their smaller version is referred to as rigatoncini, which is of a similar size to penne. It is a lot of people's favorite in southern Italy, particularly in Sicily.
The grated cheese and the sauce get in between the ridges to give you a full flavor blend of pasta and sauce.

What is Ziti?
Ziti is a classic pasta from Naples. It has a width of around 0.4 inches with a length of 2 inches and a wall thickness of 1.25 mm. It is around 0.12 inches short and around 0.25mm thicker as compared to penne. Ziti is usually a smooth pasta notable for its straight cut, unlike penne. Ziti means the betrothed or the bridegroom.
It is traditionally served as the first course at an Italian wedding lunch. It is related to Ziti candele, a pasta type that is 2 times its width and thrice its length. It has to be split to fit it in a cooking pot.
Ziti is a variation of Bucatini, a thick pasta with a hole running along the center. Buco means "hole," and it is a popular pasta in Rome and a native of Naples, Italy. It takes about 9 minutes on average to cook ziti. It is generally served with pancetta, buttery sauces, cheese, anchovies, eggs, veggies, or sardines.

They are long hollow pipes smooth in their texture with square-cut ends. Ziotini is wider Ziti version.
