I used to have pretty bad technique, and when I dared shaving one night with an OC I got a nasty surprise, very bad shave.
Thought back then that OCs are extremely aggressive, for very coarse beards and not for me.
Once I improved my technique, one day I took a '30s New and shaved with it. One of the best and closest shaves ever, I can tell you that. My skin is somewhat sensitive (if I am not careful when shaving) and I do not have a coarse beard. In addition, I always used to shave every two or three days and my beard grew not that fast.
Now that I have used OCs with success I shave daily and can easily alternate with closed comb ones (y'day I used a Merkur 11C, today a 33C, same blade brand, no probs whatsoever).
This would be unthinkable for me a year ago.
Do not listen to strict yes/no opinions on this, establish the right technique, know your face well, then you can more or less shave with anything you like or prefer.
It's how you use what you have, not just what you have. It's your skill that will get you there first, not the OC or closed comb.
