Toronto ca or london uk which would you rather visit and why?

I've lived in both cities, and currently live in Toronto. I like Toronto because I am biased. Toronto is a lot less expensive than London. However, if you really want a new experience--go to London--the history is amazing, and it's unlike our large North American cities. The benefits of Toronto is that is is half the price, you can drive here, and there is lots to see and do. London, for her culture and history--tough call.
