In general most states in the US are very similar to each other in terms of laws. There are some newsworthy exceptions, but in most people's day-to-day lives, basically every state is going to be the same with regards to laws and freedoms.
The biggest difference you'll see is different cultures, but a culture doesn't tend to define itself by the state. Most cultures in the US are centered around geographical region (West Cost, Deep South, Midwest, etc) and even then vary wildly based on the city you're in (Buffalo is very different from NYC, Sacramento is very different from San Fransisco, Portland is very different from Eugene, etc).
