Nice. You did the right thing getting 160/30.
The 330/50 would be a waste of money as it wouldn't give you that much more speed - which is primarily why you were so unhappy with your last g.fast connection (and how you were unable to downgrade).
As you say, you can see your max speed from your modem is 186 Mbps and even the Openreach equip measured it at 210Mbps before any DLM applied.
Enjoy your nice new speeds
