Actually, the Mini Client will be downloaded faster, since the file is not as big as the Full Client, but you need to patch your Sakray client afterwards, and if it starts somewhen in 2006, it will take hours to patch. Full Client is simply: Download, install, patch Anthem client, play!
I just saw your other post, you're already downloading a more up-to-date client via the All-in-One installer. That one should suffice, but don't forget to patch your Anthem client afterwards. Also, delete the folder with the old Anima client, it's simply too old. ._.
