Given where I live (very remotely!), it will be several years, if not decades, before 5G arrives here I suspect.
I use a 4G service and find it great, so my assumption (and it is only an assumption) is that 5G will just be a substantially faster version of what 4G currently does, in which case there is nothing not to love about it based purely on my personal experience of 4g home broadband.
You are probably a bit ahead of the curve though in terms of the availability of 5G routers and data plans, so they may be a bit toppy pricewise until 5G becomes more commonplace(?).
