I'd be happy with decent 4G
I remember when 4G was shiny and new and no one had it, I was an early adopter and regularly got speed tests of 50-60Mbps. Now everyone has it I'm lucky to get 10 as every cell is so overloaded. Be interesting to see how 5G holds up after a year or two. It'll probably be a congested mess and the operators will be banging on about 6G as the answer! All this is assuming you can get coverage, there are still big gaps in 4G and even 3G coverage even inside major cities.
