I've been using streisand for a while (from China) and it's great; the main reason I can see that you might want to use the linked project instead is that it has a lot less surface area so it could be more secure (it's a lot easier to harden/audit openvpn alone than all the services streisand includes). That said, if I was going to pick one protocol out of the selection offered by streisand, it would be l2tp/ipsec instead of openvpn (assuming you're hosting on digital ocean. The networks on AWS and GCE are more restrictive and you can't serve l2tp/ipsec from there). I found this to be easier to set up (the client-side software is already included in most operating systems) and to have the best performance.
