Honestly, having used both the old installer and the new procedure dozens of times each, I really do prefer the wiki page. It's just a lot more flexible and comfortable to a shell user. It also exposes a number of config files that as an arch user, you should be aware of. In that way, I find it to conform to the "Arch Way[1]" than the system it replaced.
Not to say that it doesn't have it's downsides, like scaring off new users.
