The complication with the UK system is that the quality varies enormously across the network, the South East network has very little similarity with the Northern or South Westerly network. There is no consistency, with many people their view of the system depends on the local TOC. For example, in Birmingham, at the press launch of a LM 172 , one commentator said "everywhere else has newer trains", which is utter rubbish since, for example, the Manchester rail network survives on mainly ex-BR pacers, sprinters and 323s.
"Very good regular frequent trains" is very subjective indeed, and again depends on where you travel. Would I call my daily pacer journey that? No, I wouldn't. I blame the DfT 100%, and trust me the crappy stock does get comments from those used to better trains in other areas. Perhaps I would have a different view if I commuted on a 444?
If you are looking at a whole system view, France is indeed overrated, since the focus is all on the TGV and neglect towards the branchlines. It's much the same in Spain (although the branchlines are arguably better), but if you were for example to look at Switzerland, Germany or the Netherlands you would see very frequent trains with a dense network, covering the whole of their respective countries with high-speed links integrated within that.
On the subject of fares, the UK can be awfully expensive if you don't know how to play the system, the system is so darn complicated with restrictions sharing no consistency and quirks everywhere you turn.
Now no system is perfect, the British system has its ups and downs and doesn't deserve all the bad press it gets. However, if you were to base your views on the system purely on the InterCity services or the ex-Network South East area I think you would have a better view than those who see the other side of the story. The European systems (SBB, DB and NS specifically) aren't perfect by any means, but in my humble opinion they are that bit closer to perfect than the UK. Major issues like fares, fragmentation and lack of integration let the UK down considerably.
