I have a number of thoughts on this thread.
1) "better" is a completely subjective term....it's kinda thread/topic dynamite. Since everyone has their own perception of what is "better", for them. So you will never have a consensus or realistic answer to the original question because...it simply matters on the person.
2) In what context are you looking for a "better" way of doing a setting? If you expect to have something published...well, it is going to be detailed. Who is going to publish something that isn't detailed? A few sentences about a few different kingdoms does not a book make.
3) For those that like a "less detailed" setting, which is generally for the purposes to "drop stuff in as they need/want"...this is great to ask for...but I am inclined to think this is also the people that have the time, experience, or creativity/imagination
to make things up and drop them in...hence, more than likely, they already have a setting of their own homebrewing to work in...so whatever you want to publish, they don't need it...cuz they have their own....I'm thinking of the young Ed Greenwood's (and Steel Dragons, for that matter) of the world.
4) For those that do not have the time or experience or inclination to create and detail their own world, a pre-made "detailed" setting is fine...and even great for obvious reasons...but also, even for those that have worlds of their own. So to publish a setting, I would say, the more detail the better...it might not be taken as "canon"...but it can be taken as is AND/OR has the benefit of offering/sparking ideas to the setting/world-builders among us.
So...I guess...my view all boils down to...Yes, more detail, please.
Have fun and happy setting-building.
