From 40 years with the same church choir, I have tried most hymn styles. We switched hymn books from "Hymns Ancient & Modern" to "Hymns Ancient & Modern - Revised" in 1974. Not a great change, but some of the words had been up-dated, and in momentary lapses if I'm singing without checking I still sometimes revert to the old words.
We do use 'Modern' hymns, "20th Century Hymns" and will soon be changing our hymn book Again.But I trust we will continue with most of the old standards.
Quite a few messages above give the impression that the same 'standards' are used almost week-in-week-out, this could get boring (although you do learn the hymns!). A good organist, or the vicar, (depending on who chooses) will select hymns to match the church's seasons. So a good selection can be seen over a period.

'Canting' (Chanting?) was mentioned above, so a quick cross reference to Metrical Psalms is needed here.
