Until recently I would say BT were fine for gaming, used on XBox live with no trouble for a few years, however, the last month has seen packet loss and random high pings on my line, according to BT there is no fault on the line and they even sent me a new router but though it reduced the number of packets being lost, I now synch at lower rates and still get random high pings... BT suck, but considering ALL ISP using ADSL get the BB from BT Wholesale, I doubt there would be much difference between them, all depends on the ISP's capping etc.
