Well, as a user I would prefer to be able to choose for myself whether I want posts to look similar or different to pages. 
But well, it is what it is.
What and how would I need to customize to achieve a similar look and layout? I will consider doing such customization or dropping the use of pages in favor of uncategorized posts instead.
However, a similar problem exists with category pages (as mentioned in the Different look of page and category headers thread) and this cannot be resolved otherwise than by customization since I cannot easily replace category pages.
