Please correct me if I'm wrong but I believe your taxes are based on your place of residence, not your place of work. If you are working in Ontario, that employer will withhold taxes based on the rate for that province. When you do your taxes, you will get be credited for income taxes paid to another province (and I suspect behind the scenes the Provinces will exchange the amount) but you are charged the rate in your province of residence.
As far as which province is better, that's up to you to decide and I believe it's been discussed at length in the past. My personal opinion is that you will likely pay a bit more taxes in Quebec and IMO, the Ontario Health Care system is significantly better and more available (e.g. if you live in Quebec and need to see a specialist, you will likely have to go see a doctor in Montreal). And, although I am francophone, I do not agree with a some of the language laws in Quebec.
