Joint Honours Math/Computer Science vs Honours Computer Science

Hi,

I'm currently accepted into Honours CS Co-op for Fall 2019 term. I'm considering switching into a Joint Math/CS Co-op. I'm curious if any students in either of these programs can provide any information on Joint Math/CS vs CS. Mainly interested in work load, course quality, and maybe research opportunity. I also noticed that there is no honours level project in 4th year for the joint math/cs, is this a pro of the program or insignificant?

Thanks
