I think one of the major comparisons between ISPs has always been their customer service. For which most will judge based upon experience when a fault occurs and how the ISP reacts to finding and fixing it. ISPs such as AAISP, Aquiss etc get good reviews because their staff actually understood the technology rather than reading from a "reboot your modem" script. VDSL had some steep learning curves and this is where the ISPs with technical staff won hands down.
FTTP is more stable than FTTC, fewer faults so less interaction and need for contact with Support and ultimately satisfied customers who are happy with their ISP. If nothing goes wrong, then theres little to be unhappy about.
