Steam download region

so i have a vpn connected and i want to download a game on steam and i was wondering, should i change the download region setting in steam to be my vpn location or should i just leave it as my real location? which would provide better speeds?

Your VPN location, that way it doesn’t have to travel more than it have to be, and less likely to be throttled by lazy ISPs in between.

You just want to improve speeds, not buy from another region, right?
