Comparison
I did a comparison and the majors are very similar, barring coloration and some motifs of plants and leaves.
The Soprafino Tarot, Lo Scarabeo's version can be seen here:

I compared my Il Menghello Soprafino, the black and white Il Menghello modern Dellarocca tarot and the Ancient Italian in the Jonathan Dee book (An Illustrated Guide to the Tarot) and the Ancient Italian cards (Serraville Sessia 1880).
Here's some cards from the Menghello Dellarocca:

The coloring in the Ancient Italian is sometimes an overprinting on otherwise crisp details of the Dellarocca and the Soprafino. While the majors look very similar, I saw the World card shading for the central figure and a bit of staining of red and yellow on the flame to the right of the World figure might make one miss the smoke coming from the torch.
In a comparison of one of the courts, the Knight of Wands in the Ancient Italian has a brighter colored horse, the plants near the horse's feet are small bushes and the title is abbreviated differently than the Dellarocca and Soprafino. The black and white Dellarocca uses French titles and delicate plants on the bottom of the card are only in front of the horse's legs, not in-between. The Ancient Italian abbreviates the title to CAVAL'DI BASTONI and the Soprafino abbreviates the title to CAV.DI BASTONI.
In a quick comparison of two minor cards, I choose the Three and Nine of Coins. The Three of Coins in the Ancient Italian has a very balanced motif of delicate fronds and five-petalled red flowers on top, an Arabic Three on the left and right middle sides and the coins are symmetrically balanced with an ornate blue leafy frond pattern and some sort of decorative yellow brackets sprouting from the center bottom of the card.
The Three of Coins in the Soprafino have two delicate flowers with two leafy petals around the three coins, Roman numerals on the left and right, slightly above the middle of the card and two curving leaves reaching near the bottom of the card.
The Nine of Coins in the Ancient Italian is almost symmetrically balanced. The Nine of Coins in the Soprafino has a variation in spacing and the decorative element in the grouping of coins above and below the center line.
I'd say the Dellarocca black and white follows the Soprafino closely in the Three and Nine of Coins. It would be a close second copy of the design. The Ancient Italian is a close third.
