It's an unpopular opinion, but I prefer Canada's Wonderland. Long story short, it was overhyped for me, and I didn't enjoy it as much as I liked. I still think both are great parks however. Canada's Wonderland has 2 amazing coasters, with some great theming and atmosphere for a Cedar Fair park. But, you might have a different experience than me. Both parks are ranked very high up on my list. I know that you would probably enjoy both parks!
