A few considerations - if it is rural and reasonably remote those speeds are likely correct but check the wiring at the new place - when we moved into a new house in a rural area we were lucky to get FTTC but speeds were dire - I found the internal wiring was an absolute mess* and had BT come out and chop the cable at the point it entered the house and install a new master socket - saw a significant increase in speed. We were lucky to get FTTC as 90% of the houses in the village are stuck on sub 8Mbit ADSL speeds.
Mobile signal quality could vary a lot and while speeds might be higher you will probably find the latency less than ideal if you do any online gaming and stability might not be ideal in general. While speeds on 4G were OK here I found by accident a spot where they double - for some reason a small spot in my bedroom it jumps from 30/10 to 60/25 - fortunately in general 4G here has so far been reliable with fairly consistent latency and little to no drop outs - but you don't have to go far down the road and it all falls apart.
* One of the most hideous things I've seen - it drunkenly runs around the house with a topology which makes zero sense, no sign of a master socket, and uses a mixture of spliced in 2 different types of mains cable which seem to have been salvaged off appliances, bell wire, speaker cable and CAT5 as well as standard CAT3. At least one of the extensions appeared to have been wired in using a length of grey cable from a vacuum cleaner!
