Wow, I really disagree with this one.
I have had 5G iPhones since their debut, and it was only the first year or so that things were questionable and LTE was your better bet.
But since then things have really picked up.
Perhaps you have a worse carrier - but anecdotally my experience has been quite good.
There are times and places where my TMobile mobile internet service exceeds my Comcast at home.
I have traveled extensively, road-tripping across the continent. In the past two years I have driven across or visited about 30 US states, 9 Canadian provinces, Puerto Rico, 4 European nations, and Japan. 5G is working fantastic.
But don’t take my word for it - Ookla(SpeedTest/RootMetrics) and OpenSignal all release quarterly reports.

But now for me - this is a pretty common result with TMobile:
