As @andy_mk3 posted you can get 66/22 max out of your line. On the 80/20 if you wanted more upload speed for game streaming on twitch etc then the upload speed would be good
But if you don't stream games and you are ok with your 55/10 then I'd stick with that.

could be worse though many surrounding parts have like 1.5Mbit ADSL. Still going to be a culture shock especially with so many Windows 10 devices in the household now.
