The following article may be of help: What’s the difference between PPTP VPN and OpenVPN?

The conclusion at the end of the article is as follows:

To sum up, if you are looking for high security and privacy you should choose OpenVPN. If you need easy-to-setup VPN, PPTP is a good choice. For mobile devices, both OpenVPN and PPTP can be used.

PPTP uses PPP and GRE tunneling - quite old protocols, especially GRE which may be awkward to pass by some routers. It uses TCP port 1723.
OpenVPN is more flexible - it may be set up on any UDP or TCP port. OpenVPN uses OpenSSL library with all its goods.
I don't see any reason any of them could not be routed by Ubuntu server.

OpenVPN is for you if:

  • you are blocked by Internet Provider or behind restrictive firewall
  • you are looking for high security advanced solution
  • you need additional features like Exclusive Tunneling

PPTP is for you if:

  • you need an easy-to-setup VPN
  • you want to connect from mobile devices
  • you don't want to install additional software

The above bullet list is the summary from the best comparison I found:
