You got that all wrong, bruh.
All of those other places, save for Lecce, are swarmed with sweaty tourists who will jam mobile phone cameras in front of your face at every moment. They are beautiful places, but they are overrun by memetic vacation copycat amateur tourists.
What I love about Torino is almost no tourists go there. Especially not Americans. It has the best coffee house culture in all of Italy, it is filled with beautiful grand buildings, and people dress well like adults.
Outside of Emilia-Romagna, it arguably has the best food I've had in all of Italy. It's where Slow Food started and is headquartered. Eataly started there and was fantastic before it got syndicated and became a global tourist attraction of wannabe Italiens. The food culture there is off the charts.
And the wine? Sure, people love the big Tuscan bombs and I do too. But I prefer the elegance of nebbiolo, and there it is sublime.
You don't even have to go to Torino. At least stop by, say,
Alba. Which is a gorgeous small town surrounded by walls and the smell of chocolate.
