Vancouver vs Quebec!

Currently in Canada for 6 weeks from the UK, travelled Niagara, Toronto, Montreal, Quebec and now in Sainte Sauveur for the next 3 weeks. Trying to decide whether to get a flight to Vancouver for a 3-4 night trip. It’s pretty expensive and we had planned after lots of roads and hotels to just relax in our Airbnb so definitely a change to the plan if we do My question is - is it hugely different and worth the expense/time?

If it matters, married couple with a 4 year old.
