This mall is very large, and--personally--I have a preference for smaller-scale malls because I easily get lost. Maybe I just get easily distracted while shopping?
Anyhoo, this mall seems to have slippery floors, though they appear very polished. I have even seen a live zamboni-like polisher keeping them shiny during mall hours hehe.
I have to say, that Southcentre Mall has a very large and interesting food court, complete with a nice East Indian food stand (one of my personal favorites) and the public washrooms just made me feel absolutely spoiled, like the "red carpet treatment".
Other than that, this mall is in a slightly inconvenient location being a couple of blocks from the train station. I know it's more convenient to people who drive.
