Well, as a life long resident of central Maryland, I will offer a few thoughts.
First, like most major US cities, there is the “city” proper, the close in suburbs and the more “rural” suburbs.
As a rule, the city proper is populated by two groups, the rich who live in 120 year old upper class areas and the poor.
The middle classes live in the suburbs where property taxes are a lot lower, schools are better, crime is minimal and traffic is terrible.
A one hour drive from Baltimore in almost any direction puts you in the middle of farms and rural country side - how far are you willing to commute?
The Mid Atlantic is a great place for recreation, bay, ocean, mountains, culture, history, and lots of it.
It also has lots of people, as others have said, if you don’t like people, don’t move here.
Politics leans to the Domocrat, libral side, but gets more conversvative as you move away from the city center.
As others have said, it is model train heaven - lots of good shops, many with good prices, clubs, train shows, famous modelers who have open houses, Strasburg, B&O museum, trolley museum, etc, etc. You can go to a train show almost once a month if you want to.
The cost of living is actually about average for the whole country, not as low as the midwest, south or southwest, but no where near as high as Boston, Chicago, NYC, LA (or almost anywhere in CA), D.C., etc.
The economy tends to be stable because of DC being nearby. Lots of government workers live in central Maryland and commute to DC. They bring their paycheck home and spend it in Maryland.
As others commented, the weather is nice most of the time, but summer can be oppressive with high heat and humidity - It is defenately a place with all four seasons and lots of variety in the weather. Winter can be cold for a month or two, but snow is usually light. Rarely we get a “big one” or two, but usually it snows 3" today and melts the next
