Top native Canadian Cigarette brands to buy online?

I was wondering if anybody had any opinions on the brand nexus, time , rolled gold and Dumont?

Is it worth buying the individual packs of 20 cigarettes and get a variety or should I just go with cartons? It’s just a want to try all the different types like potters and goose and things like that but the site that has the one doesn’t have the other and then the other side doesn’t sell singles or doesn’t have the brands I want or like I said sold out frustrating
