For me it was the priority access at security. As far as upgrades I only got those about a total of 3 times while being gold on UA. (Once on silver) I did enjoy being able to get econ+ for free. I've tried to complete the Global Access app twice now. I just can't bring myself to self incriminate/volunteer all of my information just for Precheck/expedited customs. As far as the lounge access, that wasn't given to me because I just reached as high as gold. Although it was provided when I did an international trip. I also did it to get the gold desk when an issue arose or that there was likely to have an issue arise. (I.e. you get an email notification of a delay in flight more than 5 hours before.. better switch flights)
