Guardian for one, certainly does vary in the cryptics and in "my time" until recently tended to be relied upon for a gentle start to the week (typically my limit) and as you will find here. may have different identities in different papers.

Setters, some, eg, Rufus may have been be known as keeping to his own way of "easier" and I'd guess some may be always "impossible" (at least to me) and others (to phrase the brother mentioned before) may "blow hot and cold"...
