Like I mentioned above, Italo is usually cheaper than Trenitalia but because the cabins on lower-class tickets aren't the most comfortable, I'll usually consider Italo only for trains that are less than 2 or 3 hours long unless the Comfort ticket class is cheaper than Trenitalia.

The debate between Trenitalia (the state-owned operator) and Italo (the private competitor) is a matter of "route vs. luxury," as both offer world-class high-speed service. Trenitalia’s Frecciarossa trains generally have a slight edge because they run more frequently and serve a much wider network, including smaller towns where Italo does not go. Trenitalia's "Executive" class is also considered superior to Italo's "Club" class, offering a more spacious 1+1 seating layout and high-end catering. However, Italo is often praised for its modern, stylish trains and more aggressive promotional pricing; for a direct "city-to-city" hop like Rome to Milan, Italo is frequently the cheaper option. A major advantage for Trenitalia in 2026 is that it allows you to book regional and high-speed connections on a single ticket, providing protection if a delay causes you to miss a connection. Essentially, if you want the best price and a modern vibe, choose Italo; if you need the most flexible schedule or a connection to a smaller destination, Trenitalia is the "better" and more reliable choice.
