LLC in different states

Sooo I live in Massachusetts…..do you think it’s beneficial/ legal to open the LLC in New Hampshire?? I did some research I know it’s technically legal I just have to file a foreign one but like idk is that even a good idea. It’s way cheaper and the taxes are better than Mass…I think🥴 but I’d have to pay double taxes and such…..just want come advice on if it’s beneficial in the long run not just in the beginning to cut cost. Thankss☺️
