Among English Speaking world. absolutely Canada has the shortest route toward PR (If you ignore US Lottery or US marriage green card, which are definitely not compared to express entry as they are not following a systematic pattern). But Canadian education comes with massive expenses.I agree with you there but is there any other English-speaking country with a shorter timeline to PR than Canada? I've checked Australia and NZ but the process seems even more hectic.
For a rich kid who can afford Canadian education, or someone with an enough strong academic background to get funding from Canadian universities the study route should be number 1 priority without any doubt. If anyone on this forum falls into either of these categories, I highly recommend you to forget about waiting for FSW draws immediately.
