Are trade shows in the US really worth attending for business growth?

I’ve been thinking about attending one of the large exhibitions in the States, but I’m not sure how useful it can be for a mid-sized company. On one hand, people say it’s a great place to showcase products, but on the other, the costs for booths, travel, and logistics seem overwhelming. I’m trying to figure out if the benefits justify the expenses, especially since it would mean flying a whole team. Has anyone here had real results from such participation?
