Basic User approach Like Speeds & Security
In percentage any one can describe
Ikev 2, Originally intended for weaker hardware or mobile vs Open VPN
Speed 90%
Safety 90%
Compatibility 90%
Open VPN
High processing needed , on phones can be hicky with connections and uses more battery.
Speed 60% ( if hardware weak if router speed 10% if powerfull desktop 90% )
Safety 90%
Compatibility 90%
Wireguard
Speed 90% ( Low powered devices also 90% )
Safety 90% ( cause 100% isnt possible ! )
Compatibility 70% ( some issues with some wireguard implementations with a few programs )

they also explained each protocol very nice and simple and neutral and in depth

Glad that someone asked because I have no clue what’s going on
Best overall Wireguard, OpenVPN is more old and tested and if you have issues with your ISP about connection drops, you can use it with TCP 443. IKEV2 is closed source by Microsoft and Cisco so I will never recommend it.

Scroll down to “What are the connection modes?”
Don’t use Nord VPN use Proton VPN or Shark. I wouldn’t use any vpn if it not those 2 besides wireguard and i use them as a server rather than the vpn. but proton has a few servers left in Russia AND CHINA which no one has had since the war. and proton is very flexible w its abilities don’t sleep on it
If I am on Fiber Optic internet, and my speed is steady and don’t get disconnected, then its okay and better to use Wireguard than OpenVPN-TCP?
Everyone has Access to those info and that is obviously windscribe perspective
We are here to hear from the people Day to Day life experience about those services like which servers they have tried what change they observed which types are good bad ugly these things we care here a lot
how you know it? windows 10 has not Strongswan support as i know
OpenVPN TCP is the slowest option of OpenVPN, it’s helps to bypass censorship, if you use i.e TCP 443 port, Wireguard is a newer protocol and it’s integrated in the core of the OS so definitely it’s much faster and use less resources, I will recommend Wireguard always as first protocol to use. Just use Wireguard 443 UDP
Thanks a lot man. I use Expressvpn and its Wiregurad protocol, named Lightway, has also TCP. Do you recommend to use Lightway-TCP or again you recommend its UDP? Again thanks.
I asked the question because of this video:
Just choose Wireguard, Wireguard works only in UDP so there is nothing wrong with UDP,
Ok, so if you confirm that I shouldn’t worry about the reliability that TCP of Lightway might have over its UDP, I will select UDP.
You can select whatever you want, I just gave you recommendations
So I must not be obsessed and also worried and keep repeating in my head: I would have packet loss or corrupted video download or file download, etc, if I use UDP?
Wireguard is UDP for now, and if it could make a file or movie download corrupted, the developer would not release it to public, am I saying correctly?
Completely, I’m using UDP with OpenVPN since many years and never had any issue, and with Wireguard same, so UDP is good enough if not Wireguard project wouldn’t use it as default protocol 
I now use PrivateVPN. They don’t have wireguard protocol yet.
Thier default protocol is OpenVPN-UDP. As you see in:

So, I will use OpenVPN-UDP.
Yes, thanks. Also, a tech support of other VPN I was using, told me this before:
Yes WireGuard UDP should be faster and I only recommend TCP if you have networking problems (like packet loss or unstable connection).
OpenVPN UDP is fine, look instead for IKEV2 it has better performance
