In my opinion not at the moment.
4G is almost everywhere, and if you in a city, expect very good indoor signal.
I tested out my new phone on EE's 5G network, I am in one of their declared 5G cities, I am close to the city centre, and indoors it keeps flipping between 4G and 5G, had to root the phone to fix the behaviour, and outdoors the 5G signal is weak enough that 4G has faster speeds.
When I checked a 3rd party site which gives info on the cells, out of 14 cells in my immediate area, only 2 of them have 5G enabled, all 14 have 4G and usually multiple frequencies as well. It seems 5G has been rushed so they can advertise the service, but its nowhere near as usable as 4G.
