A spool valve should have less kick then a poppit all though my g6r is as smooth as some spools, well broken in clones and dm's are slightly smoother ,plus you said the g6r had about a case through it? That thing is gonna get way smoother once broken in and fine tuned.
Not hating on the demon at all I actually am interested in it but they should be compared again once both markers are properly broken in and fine tuned to get more realistic results, you didn't really state why the demon was better in your opinion other then a little smoother.
The g6r is very easy maintenance and a beast on air efficiency but will always have slightly more kick I believe then a well broken in demon I'm just curious to see the demons efficiency numbers once it is broken and fine tuned more once the seals break in.
It's all personal preference in the end
