It's one of my least favorite airports in Europe. The number of times my luggage got lost there alone is enough for me to avoid whenever possible. The shops and restaurants are also extremely bland.
The needed context seems to be that the person you are replying to is German. I don't love Schiphol either, but it beats any German airport (looking at Frankfurt in particular).
I like Heathrow when travelling to or from London. It's huge, but there's public transport to each terminal, a reasonable selection of restaurants and generally somewhere to sit. It's fairly quiet.
Changing between terminals at Heathrow is much less fun.

I decided to stay at a Heathrow airport hotel a while back. Turned out I had to change terminals and I'm pretty sure it took me at least as long as getting a shuttle bus to one of the hotels would have taken.
You often have to walk quite a ways too.
Overall though Heathrow is pretty good among the large European airports.
I actually kinda enjoy the distance between terminals. After a long international flight, I deliberately take the tunnel, and skip the moving walkways. As long as I'm not rushing to make a connection, the walk is really nice.
Copenhagen airport is my favourite too - note however that Arlanda T5 is being expanded at the moment and it seems like it will be a lot nicer when they're finished. The security stuff is already much better: no need to unpack laptops etc. from hand luggage when going through the new section. T2 is still quite sucky though!
