Gandi is a special case. Also, IT people with decent skills can go anywhere. So his case does not apply to that of an average Joe/Jill. Tony could not get a PR, no offense to him lol.
Things I remember. Drugs, homelessness are much worse in Canada. I searched, I could not find anything like what you see in Vancouver etc in Aus. Salaries are 10k lower in Canada per year after conversion. Better weather and life expectancy is longer in Aus. Cost of living used to be lower in Canada, no longer. Their PR is harder to get in Aus, I would say it's more secure, easier to kick out temporary residents. I kind of worry that when shit hits the fan, we will have huge crime rate in Canada, too many people are let in without much security checks.
Update. Looked at the channel and comments. People agree Aus is better, but very hard to immigrate permanently. My impression.
