I had mostly positive experiences, but in general support after birth seems to be lacking.
my antenatal breastfeeding class was very motivational, but little information about how to manage common difficulties, eg I was told not to bother buying lansinoh cream as after this class my latch would be perfect!
We had a private birth and our midwife stayed with us for an hour to help with our first feed, and then I called her back to help me feed every time until I had it right. Overnight a midwife was always available to help immediately. Invaluable, sadly midwife staffing levels on the NHS postnatal ward are shocking. Some midwives know a lot about breastfeeding and are enthusiastic and have practical advice, others just read the 'breast is best' information in your notes to you and suggest a bottle if you are struggling.
Also postnatal wards are often noisy, hot, lack of privacy, poor access to fluids, no wonder lots of women struggle.
A few days after discharge I was having trouble with positioning and a local NHS breastfeeding advisor came round within a few hours to help. That was fantastic.
I have been so several breastfeeding cafes and seen some very detailed assessments and carefully thought out advice, and some very wishy washy vague advice.
I phoned the UK breastfeeding helpline in tears and couldn't get through for half an hour, and when I did she misunderstood my difficulty and I was too upset/ embarrassed to explain it again.
I phoned a Doctor friend, also a mother, and she suggested a bottle of formula in the evening

I found the internet very useful, Kellymom website has good practical advice, and there are some support groups on Facebook.
