I used both and could not tell you the major differences. I feel like they are equivalent in the bread and butter features. Most people don't use 99% of the functions they bake into these. Just use it to hold the syllabus, maybe hold the slides, submit assignments, and spreadsheet for grades. All stuff you can do with email + spreadsheet already. Maybe throw in a shared drive for larger files, which every university in the country already pays for.

do you mean equivalent ?.

Blackboard got a lot better in response to the flood of customers heading to canvas.
