Ziggo does not provide 5-10x faster internet at around the same price. That's a huge exaggeration.

58,50 EUR a month for 200/20 mbit (if you can get that speed over VDSL2, that is)

54 EUR EUR a month for 200/20 mbit (provided they deliver at your premises)

Where Xs4all is more expensive, is TV, which is actually KPN's.

Previously I had the choice between good quality VDSL2 from Xs4all (or KPN etc) and slightly cheaper Ziggo. That's before they merged with UPC. I consciously picked Xs4all because they deliver a far better service.

When I switched in 2012 I went from 40 Mbps VDSL down, from which I got maybe 14 Mbps tops in practice to a 100 Mbps down cable connection, which I frequently hit. The shop I worked at similarly got a boost from a 40 Mbps VDSL (really 25) to a real 150 Mbps down around the same time. In 2016 I moved to my current apartment and 40/4 was still the max, while I could get 300/30 from Ziggo. Hence my 5-10x claim.

YMMV depending on the copper quality of your neighborhood and distance to the neighbourhood connection point (I don't know how to translate "wijkkast").

I have little experience with VDSL2, but in my experience xDSL delivers a lot less than the theoretical max and has a lot more variance than DOCSIS.

Same here. Looked at xs4all when I moved to Amsterdam in 2010. Went for UPC which had a much faster connection, in 2015 they merged with Ziggo.

Incidentally, KPN announced yesterday that they are starting a rollout to 1 million households for FTTH.

That sounds really nice, albeit 10 years too late. It's a shame XS4All won't be around when/if I finally get access to fiber.

1 million MORE households on top of roughly 1/3 of all households that have fiber. :)
