Actually, Maxis fiber is currently the best for playing BF4 on the SG servers. They do depend on TM HSBB for last mile access, but beyond that, their Internet connectivity is completely theirs.

With TM you get nasty 40ms - 80ms ping (with lots of packet loss with the latter) due to congestion.

With Maxis, it's a steady 10ms++.

In fact, the situation with TM is so bad that I setup a VPN for my close friends, so that they can take advantage of my Maxis connection.

Nope, no sudden lost connection - but maybe that will happen if you're on a private IP.

Other than that, I know that their connectivity to Blizzard SG is bad. Don't know about others because these are the only two games I play
