The answers to your questions will of course vary from department to department, Jamjar, and as an arts student I'm not sure I can be of much help!
My experiences were on the whole very variable. I had some lecturers who were fantastic and others who were about as clear as treacle in their explanations; as a joint honours student, I had one department with excellent pastoral care and one with pretty awful support; and as far as personal tutors went, I had some who were very attentive and offered high quality one on one tuition, and others who didn't even reply to emails.
Academically again, things were very variable - when I was invigilating at Oxford's collections (undergraduate beginning-of-term exams) last year, I was able to see the difference between Exeter's style of teaching and Oxford's very clearly, as the Oxford exam questions (I refer to the papers for English Lit) were more like AEA/S-level style (more open-ended, more provocative, more interdisciplinary) while Exeter's exam questions were more like A-level style (only really aimed at the texts you'd actually studied rather than encouraging you to go above and beyond; quite conventional questions). If the lecturers in the English department simply didn't agree with you, you didn't get the marks (on the whole - of course there were exceptions), whereas I found that the Classics department were more challenging and open-minded in their approach.
So you see - different people will all have had different experiences with various departments.
