Depends on your QOS settings my friend also I really doubt exit lag is going to do much did bit of research just seems to be something similar to like a vpn.
Generally a VPN will help depending in your area that might be the reason for the lower ping can't say since you would have to personally collect data to figure that out
When setting up your QOS and testing benchmark focus on the ping under load which is the buffer bloat in which you basically want the least amount so the experience is as responsive as possible.
