Most of TM's customer using streamyx does not have a choice. Unifi is not available at their location. 

not everyone have option to choose unifi, especially old taman/kampung/flat. the cost needed to install unifi fiber is not worthy in TM view. nid to korek more. nowadays they plant the fiber when house is being developed. furthermore, IINM TM will upgrade the Streamyx capability at those area to support 8mbps. so, area that suddenly have 8mbps support will not get unifi.

I quite didn't understand what u mean by Unifi need internet to be activated upon installation.

i believe it's the same. but there's no HyppTV on streamyx package. u can opt to it urself as addon IINM. but the quality is not as good as unifi la.. i believe unifi have separate connection for HyppTV while Streamyx will tumpang on ur internet line. so if u download or torrent, ur HyppTV will be affected and buffering..
