Re: Will the KM be an upgrade?
I have an Obelisk and two KM's. The biggest difference you will notice will be the purge. KM's, because of the closed chamber design, will purge easier.
As for the draw, if you're using the Mya hoses it came with, you will notice they are more restricitve than the hose that comes with the KM. With Razan or Nammor hoses they're almost the same.
There's also less setup/cleanup with the KM because it has fewer parts.
