A lot of factors go into speed. Being close to.a 5G tower and the type of 5G service impacts speeds, and broadband comes in a lot o speeds that depend on how much a month you pay. 300 vs 1G has a big price difference, so a hotspot, may be cheaper and faster at the lower end of the speed spectrum. So a hotspot may be a better value than hard wired; it depends on the speeds you need.
In addition, while d/l speeds may be faster, u/ls may not, which is fine for many uses but may be an issue for gamers.
Then, of course, there's latency...
