I think Quora because it has more users. musing is limited to steemians and most of the questions asked are blockchain related.
I like both for different reasons. Quora has been going for a long time and so is really good for a broad spectrum of answers to different questions on many different topics but obviously there isn't the chance to get rewarded for your answers and content. I do like musing for this reason, although i wish it wasn't always about money i guess, unfortunately, it is. The fact that often people will answer your question and not even upvote the question beforehand shows me that people are strongly motivated by earning steem but are reluctant to support others in doing so, which is kinda messed up. The problem with money, wherever its involved, is it promotes greed. People spamming questions that they don't even care about the answer to, reflected in the fact that often people don't even upvote answers to the questions they ask. Sorry, i realise i am going off the topic of your question but i guess i would summarise like this...Musing has the potential to be the better platform if it doesn't start to incorporate the issues that steem has i.e. no votes for new members or good content over spam and the overuse of bots.
I have asked one question on quora in the past 6 months and several on musing in the past month so i guess that says everything though.
Quora certainly has more people asking questions on it, though I suppose that is due to its age and external reach. I like musing for the ability to answer questions and have them posted to the Steem Blockchain. I try and ask a question every now and again, just to keep conversations going. Perhaps we should all do that, just to help build up the site. We are a bunch of community builders, after all...
By the looks of it, they have the same objective. Quora and Musing has almost the same features and both are "question and answer" platform.
But honestly, Quora has a better user-base and the development team is larger than musing. We all know that Musing is funded through delegations and there actually has no pledge of support financially aside from the delegation received. Quora is better funded and their employees working for them are quite bigger and it's the reason why Quora has been smooth because they have a lot of people working on things that gets the platform better.
I would have to say they are both better in their own way, for instance, Quora is better because they have more users. I've been on Quora for a while now but comparing the aspect of making money is the big thing that makes musing better in it's on way earning based on upvotes of your questions instead of just earning based on ads impressions & how much they (Quroa) thinks the question is worth when in the Partner Program.
I would say currently Quora is better as it has been around for much longer, and thus has a huge knowledge base and had built up the trust of millions of people, I think in time that Musing could compete with Quora, but it will just take time to gain market share and penetrate this market.
The one thing that Musing has that Quora doesnt is incentivised rewards, meaning we are paid for our contribution. This is HUGE and means that (most of the time) people will put more thought into their answers and the quality of answers will be higher.
I'm banned on quora for doing some advertising so fuck them.
