While Stratics has more content overall, I also find it more difficult to navigate, clunkier and slower when it comes to finding information other than news on the front page. I think wiki-based approaches are better for many of the reasons outlined above. Wiki sites tend to be cleaner and you can usually find the information you want more quickly and it's also easier to find related information from that point (surely everyone has looked up something on wikipedia only to find themselves clicking on related terms in the article, reading that, and so on... =P)
An example would be when I needed to find out what the hell Casting Focus was. On a wiki based site, you type it in the search box and if it has its own article, you get taken directly there.
Using a google search tool, you type it in, get taken to a third party site and you're lucky if a link to the article you want is in the first five or ten hits. Your other option is to navigate the huge list of unwieldy menus.
(On a side note, for those criticising people for wanting things NOW NOW NOW, information like what item properties do is stuff that you should find in any manual, not in a strategy guide. It's not unreasonable to want to know those kind of things.)
Also the system of updating content on Stratics might have better quality control, but having to post an email to someone who will then verify and post the content means you have a one person bottleneck in the system. What happens if suddenly, people decided to submit hundreds of updates to the Stratics content? It'd be great news no doubt, but also a lot of work for one or two people to handle I think.
I am not saying either site is better, both have their advantages and disadvantages. I am just more familiar with and prefer wiki-based content systems these days I suppose. But I don't see the issue with having two sites around with stuff on.
