Not the person you are asking, but definitely yes. Bandwidth isn't the only metric at play here. Bufferbloat was horrendous with Comcast so latency varied wildly depending on what was happening on the network. The only way around it was to cap download and upload to 80%, and that's a large dent on the already anemic upload. And I had to cap client upload too, otherwise one client could easily saturate upload and now not even TCP ACK packets were being reliably sent. The main problem isn't cable per se, is the asymmetric link. EDIT: Also 1Gbps symmetric allows me to backup my NAS offsite without impacting anyone else.
