Not sure why you're expecting a different answer here, than you were provided here:
You were told VERY explicitly, that OpenVPN is more secure than PPTP. It still is; doesn't get much simpler than that. Yes, you are more vulnerable with PPTP than you would be with OpenVPN, but anytime you open ANY port, you expose things to attack.
