Oh and we have 3 M&S food halls so plenty of supermarkets!
I love being able to go on cliff walks on nice days, finishing work at 5pm and being in the sea at Cobo by five past where, incidentally, there is no sewage. I swim there practically every day in the summer and quite often in the shoulder months. You can get fish and chips and sit on the beach watching the sunset. Buses are currently £1 per journey so really cheap to get around. The downside is the the buses don't run late at night and taxis are expensive.
Internet shopping is relatively easy these days. There are still some places that don't deliver to the Channel Islands but there are ways around this or you shop somewhere else.
I am well travelled and I think Guernsey is incredibly friendly. People will talk to you, if you look lost they will offer to help. Lost phones, purses, wallets etc get handed in to the police station, maybe not all the time but most of the time. I can leave my bag on the beach and go down to the sea to swim and when I come out, my bag is untouched.
We have amazing restaurants, no fast food chains like the UK but I personally like this. Yes some of them can be expensive but not all and you get what you pay for.
