Compare between UM and HEC in Montreal

The first time i saw UM, i was like surprise, because it s too big and it seems like a city, in compare with my university in Montreal (HEC), In Hec you found only one or two building, and between them you have to take a bus. but i think because Hec it 's only for business study
In hec it's a new building and with a new technologies too. here the campus or a residence when we are : Arthur mauro, it s too beautiful and so clean,there is gym room and other services, and if i want to compare with Hec , i can't do it, because, i never was there.
