I used Spectrum for four months but because of my L2TP setup, DOCSIS ACK suppression doesn't work; it's TCP inside L2TP UDP and then ACKs are then sent over the wire. This meant sluggish internet under load. Spectrum did install a high-split amp but it's still not turned on afaict.
Row townhouses in Brooklyn and Queens have Fios, but not in Manhattan. I wish I could just do a NYT ad but that'd force me to liquidate a decent chunk of my E*Trade and J.P. Morgan accounts.
I am right now visiting Belgium and I saw multiple towns, including historic neighborhoods with Proximus fiber splitters: Brussels, Antwerpe, Ghent and Bruges. The fiber and Telenet Coax is so well organized when compared to NYC's coax mess. However, where Fios is available, Verizon does an okay job with organizing fiber.
Verizon said killing line sharing would bring more fiber. Yet Proximus built fiber in historic cities more than Verizon did. I don't believe Orange France legally has to share fiber, but in return Orange can't block Free/SFR with payola deals.
