If you play FPS games only I would go withthe ragnarok however if you play many different types of games I would choose the macro. Personally I think the macro is the best controller outthere period.
if you mostly play CoD and other FPSers you should be fine with the Ragnarok. If you have ever thought to yourself... man I wish I didnt have to keep pressing this A button (or anything else) then you should get the Macro.
I'm pretty sure they won't be doing customizations on the macro controller. There is a limited number of macro controllers left, and they are all pre-built. Viking360 is moving forward with the Ragnarok models for now. The macro controllers cost too much to make and there is not enough demand for them to make much profit. Odin recently posted explaining further on the matter in a thread found here on the last page if you want to check it out: http://www.vikingforums.com/showthread.php?3780-PS3-Ragnarok-DIY-chip/page3
So for now there are only customizations on the Tyr's Hand and Ragnarok models unfortunately. If you mostly play FPS games though or Call of Duty, save some money and get the Ragnarok, it has pretty much everything you'd want and future updates will be coming shortly with a bunch of new features. There's a thread I made about that here: http://www.vikingforums.com/showthread.php?3837-360-Ragnarok-Driver-Software-Update-Ideas
