Why is my LTE faster and more reliable than 5g

I have an iPhone SE (2022) in Sarasota FL and 5g is horrible and unreliable. I had to switch the phone to LTE to get any reasonable data activity and it’s much faster and more stable than 5g.  I did many speed tests at different times of the day and LTE hands down is far superior to 5g.  I don’t understand why? Any suggestions?
