I intentionally wanted to try out both providers. From service quality, I cannot tell a differnce. Both setups were straightforward and there have been no issues with the connection within the last two years (none of which I’m aware of, at least). So I can recommend both of them!
From a commercial point point of view, I don’t know what current terms and conditions are, you’ll have to check out their websites. I think the overall costs are similar for both providers; in my case, it’s much lower than paying for a Swisscom line…
Let me know your experiences if you’re going to set up a new configuration.
