"Intriguingly a lot of properties that could have a cable service have preferred to stick with copper. One may well wonder why."
In fact everyone on that cable service is also stuck with copper, since that's what the coaxial cable in question is made of!
Having used both, I found FTTC much better in actual use than Virgin's DOCSIS. Both are copper as far as a green street cabinet, then fibre from that point on - but FTTC gives much more consistent throughput, particularly for upload.
Since someone asked earlier, I'm with aaisp.net (Andrews & Arnold), and extremely happy with them. I did have a fault - which we eventually traced to a bad backbone switch port within BT's core network. Finding and fixing that required SIX Openreach visits to do line tests, before BT Wholesale would escalate the matter to BT TSOps and on to Adhara (the backbone management team at Adastral Park). Any other ISP would have given up; A&A didn't bat an eyelid, just kept pushing harder and harder in different bits of BT until the fault was fixed. They don't cut corners, so they aren't cheap - but they will do whatever it takes to get issues fixed. Bandwidth options for Home::1 users are 100, 200 or 300 Gb per month (£10 difference between each), which will be fine for virtually anyone. (If you use over 300 Gb per month on the BT backbone, you'll be costing your ISP an absolute fortune.)
