Both!!! Remember . . . the business goal is to get views on an online article!!!
Views are determined by reader engagement or length of time on an article. That is also an element for ranking articles in Google searches. The goal of course is to be on page one. Google measures both content and context (Presentation).
There is an adage 'Content is King'. That is why HP has the Quality Assessment Process. For what HP looks for (Informational / Creative) see: https://hubpages.com/help/hub_hop_table#informatio...
But, since before '97 research / statistics point out web readers 'generally' don't read beginning to end (Analytical Reading). They scan / skim an information article and may spot read. So, context is as important. Footnote: That method is taught today in schools for reading for information.
What is context?
*** Title - key words and length. (Recommended is 60 characters or less. 55 characters are displayed by Google)
*** Opening paragraph
*** Call Outs
*** Paragraph structure - Topic, supporting & concluding sentence
*** Paragraph length
*** Article summary

Hint: Mobile viewing is on a steep rise.
So, review your Hub in Mobile Preview. That is available in Edit mode at the Top Left. Easily seen it is linear and narrower. Consider a mobile reader will scroll through the article first.
That is where call outs and images are important. Today it is recommended to center images and not off-set to the right. Of course the total length of the article with images in mobile view will become longer.
*** The average viewer stays on a page for 15 seconds to decide if to read.
*** They scan / skim or scroll to see if it will answer their question / interest or perhaps to get the jest of a How-To article. Average time is 60 seconds.
*** The average reading speed is 200 - 250 words per minute.
*** The optimal read time for reader engagement is 6 - 7 minutes
*** So, the optimal word count for an article is 1,200 - 1,500 words
