I'm still a fan for cost reasons of FTTN, because I think with Coax in the last mile, you can deliver fantastic performance, so long as you're not also trying to delivery video too. Furthermore if you actually run Coax in duct for buried circuits, its easy to replace with fiber later.
Our telco converted all its infra to FTTN via fiber. So, I've actually have fiber connection up to the front of my building, then it's terminated and distributed via VDSL to the street. I have a 50/8 mbps connection at home and, it gives all the performance it can give. The telco keeps the speeds a bit higher to handle VDSL overhead, so we have a real 50/8 mbps IP connection at premises. I'd rather not rewire my home…
I have Sonic fiber in SF. 1Gbps symmetric, over a "fragile fiber" run directly into my home. It works quite well. The drop cable is pre-made in standard lengths with weatherproof connectors. The glass is embedded in a large-ish diameter substrate that resists sharp bends naturally so the installers don't need to take special care to prevent losses, just don't try to force the cable to bend beyond what it wants to do (very different from your standard fiber patch cables in a switch room). It is robust enough you could cable staple it to a wall without issue. Terminates in a tiny ONT that gives me Ethernet on my side.
They're deploying 10Gbps for all new installs and I'm eagerly awaiting my upgrade. No change to the fiber itself are required, just swapping equipment on both ends. This same fiber can do 100Gbps in the future if the need arises, possibly more. No coax plant can come close. The fact that an independent ISP can do this for $40/month and make money at it proves the economics.
There is no reason not to run fiber unless you're more focused on rent extraction than investing in your business... at least in suburbs and cities. (See ATT's public comments and focus on milking wireless while dis-investing in physical plant as an example of goosing profits because they don't face real competition in most of their service area).
