Fixed LTE via Afrihost (Rain). Average speed around 20. No Telkom landline rental, no contracts, no grief. We have fibre installed in Norkem Park, but it seems that connections will only happen next year. Until then I am quite comfy with my current connection.
VDSL, because it's the least expensive fixed line service available that offers a dynamic IP address range from ISPs, and the ability to easily switch between ISP data accounts by simply entering a new PPP username and password, while still offering Fibre comparable performance. It also offers a relatively decent upload speed for my cloud backup needs.
