Like you, I've heard different pros and cons of both methods. Personally, I just upload whenever I can without exerting myself or failing to meet my commitments. I think it may be better posting at least once or a few times a day if you're looking to get more subs quickly but as far as views I guess it would make sense to post weekly to give people a chance to view/react to your newest video.
