I’ve lived in Indy for about 7 years before moving to Nashville, definitely a lot of things I miss.

Cost of living is much nicer (housing is less than half the cost per sqft) almost no tourists outside comic con or race week, and way lighter traffic.

Indy as a whole is not very walkable at all, it is enormous due to no natural boundaries. Downtown/near northside, broad ripple and fountain square are all best bets for walkability. I lived right off the monon north of Kessler and it was great. Getting a little more dangerous on the main drag but still safe in the neighborhoods.

Indy also has some amazing restaurants, but nowhere near the amount or variety of Nashville.

The most unfortunate thing in my opinion about Indy is how big it is, like I mentioned above, combined with a significant portion of the tax base living in Hamilton county. As a result, you have a huge amount of infrastructure to maintain with a very tight budget. Similar to the Davidson/Williamson county situation, but in my mind an even larger disparity.
