Some are better than others. I use NordVPN but not just specifically for games, but I have had a couple of routing issues, it was screwing with my Discord too.

But if you are looking to reduce ping.
An alternative I've seen recommended is ExitLag, which seems to have game specific configurations and is designed as a latency tool and not as a VPN.
They have a free trial, so worth a try at least. Though as always, it's dependent on the cause of your high ping.
