Which trade show signage makes the biggest impact?

I’m preparing for a trade show in Houston and I’m trying to figure out what type of signage setup makes the biggest impact. I see companies using custom booths, retractable banners, table covers, backdrops, even floor decals. From a design and branding perspective, what elements actually make the biggest difference in attracting traffic? And is it better to work with a local Houston signage company for this type of project? Would love to hear from designers who’ve worked on trade show displays.
