I've lived in Vancouver all my life and I've traveled a fair amount. Personally I think Vancouver is the best city in the world. Of course I'm a bit biased

But it is a great city.
It is incredibly multicultural, which can be a bit of a shock for people who come from very homogeneous city, but if you keep an open mind, I think the multiculturalism is really what makes Vancouver great. As for hearing that the people are "unfriendly", well, I'm sure there are some unfriendly people, but by and large I think people are really nice and helpful.
It does rain a fair bit (it's in a temperate rain forest after all). But that makes the forests, parks and nearby mountains incredibly lush and great pretty much all year round. It really is a stunning city. Poco is nice too, from what I have seen of it. Also, it is more of a suburban area, so I would imagine the crime rate isn't too high. Certainly not as high as Surrey and way lower than east van. Although, I do think crime rates have been going down.
As for arts, Vancouver is way up there imo. A trip to Granville island or just downtown Vancouver will show you that. There are also usually local art community centers where kids can take art classes, dance and music lessons. Piano lessons are offered in private homes as well all over the city. I grew up with a great appreciation for art and culture, going to the ballet and symphony with my parents and traveling to Granville island, deep cove in North Van and the Vancouver art gallery.
Winter and water sports are also readily available in Vancouver. Kayaking, canoeing and rowing are all popular in many communities in vancouver, and quite affordable as a daytime adventure. Of course, skiing, snowboarding, tubing, and snowshoeing are all available in the winter season on the local mountains. There are also skating rinks everywhere.
In addition to winter sports there are usually public tennis courts, soccer fields and hiking trails.
And the best part is, I don't even work for Vancouver tourism

I just love it!
It's always hard to move to a new city, but if you keep an open mind and make friends with locals, and take trips into the city, I'm sure you'll love it too. Best of luck! Message me if you have any Vancouver-y questions
