Yeah I'd say you're pretty much correct. Looks like you did your research good job

1) Filco: Most expensive but also do feel most solid. However some find the price doesn't justify quality increase. For example, almost 2 times more expensive but not 2 times better.
2) WASD: Seems a solid choice never heard any complaints. Though V2 is on the horizon so if you plan to go with this then you should wait.
3) Das: Like people said Ultimate and Mac Edition are still Costar. In my opinion quality feels similar to Filco but Filco still feel sllightly more solid. Gloss finish is love or hate.
4) Rosewill: Seems like the cheapest full size choice but I don't know if the mini b connector issue is fixed or not. Goes on sale a lot however buy at your own discretion.
5) CM Storm: Only QuickFire Rapid and Trigger are currently Costar. But they're coming out with QuickFire XT which is a Costar full size. CM Storm has the best money to quality ratio but if you want full size you might have to wait.
Now keep in mind some brands carry in a lot of major stores and some you can only order online. To me that since I can pick up Filco, Das, and CM Storm locally so price wise they actually have an edge over other brands which you might have to pay for shipping (Which isn't cheap for mechanical keyboards).
