geeker - as far as I'm concerned it's very much much 'each to their own'. One member of my family favoured quick (non-cryptic) crosswords, another used to do only the General Knowledge puzzle in the Sunday Express, while my mother loved tough cryptics. I don't consider any of them cretins, and they all got enjoyment from the puzzles they tackled. Personally, I find the Guardian back pager abhorrent, but I know there are plenty of solvers who would say that it is their favourite crossword.
The important thing is surely that there should be a range of crosswords available such that people have the opportunity to try a variety of different puzzles to find out which they like best.
You're quite right about Chambers, but I would add that there is no need to acquire the printed version as it is available now for pretty much any smartphone, tablet or PC.
