This is a most excellent place for technology news and articles.
I'd never trade my VDSL 250 for anything TV cable based, at least where I live. It could be 10 Gbit/s and I wouldn't care. Some neighbors have Vodafone cable and it's probably the most unreliable internet service ever. Also, latency is higher. Of course depending where you live, ymmv.
Choosing an internet provider based on the advertised download speeds is like choosing a camera based on megapixels.
All that being said, copper is obviously crap no matter the tech, and I'm happy that Deutsche Glasfaser will most likely offer real FTTH in the coming years, which means we'll get high-quality, fast connections.
