What each can be found with research so my bet is your question is something else.

Let's hear that other question.

As it stands your VPN provider will choose which will be used so there's that. For me the irksome truth is not all VPN providers were telling all about their services. For example the entire reason for VPN is to stop Internet tracking.

What good is that if your VPN logs your use?

Difference between VPN Protocols

By now it’s become quite obvious that many VPN encryption technologies are certified and developed by the National Institute of Standards and Technology. But, shocking, new revelations from Edward Snowden have shown that the NSA has been working for years to subvert and crack these technologies. This definitely raises the question “Are these VPN technologies really safe”?

I doubt the protocol is worth much.

As to security here. What's more interesting is whether your VPN choice logs what you do and if they suffer from other leaks. The DNS leak was well known but if you intention was to use the Internet securely and leave no trace, the Five Eyes issues have to be noted as well as the VPNs that log and leak.

Protocol Differences
by HomeTechHacker / June 25, 2018 9:04 AM PDT
In reply to: VPN

If we are talking purely protocols and not services I can give a bit of an opinion:
PPTP - fairly fast, native to most devices, encryption is okay
L2TP - high encryption, requires higher processing power than the other two protocols, native to most devices
OpenVPN - high encryption, but still performs at fast speeds even on high latency networks. Extremely reliable and stable, supported by many devices, but probably not as many as PPTP or L2TP.

I personally use OpenVPN the most and have it setup for remote connections to my home network.

If OpenVPN is available, I'd go with that in most use cases.

Here are the differences between the protocols.

There are several differences:

PPTP -- the oldest one, straight from the Windows 95 times. Though it isn't really secure so there was a need for different protocols.

L2PT -- one of the newer protocols, has some security flaws too. Fun fact: the only supported protocol on Chromebooks.

OpenVPN -- not that widely supported, but one of the best. Secure and fast.

IKEv2 -- the newest protocol. Wanted to mention it, because I am using it on my MacBook and it is not only secure but fast too, I like it more than OpenVPN.

Depends on the situation, but if you can use OpenVPN or IKEv2, use these.

PPTP -- the oldest one. Though it wasn't really secure so there was a need to develop newer ones.

L2PT -- one of the newer protocols with its own share of cons.

OpenVPN -- One of the best. Secure and fast.

IKEv2 -- the newest protocol.

Based on these protocol choices VPNs are developed...you can check for different reviews and choices here at ****
