Congrats on getting a distributor..not an easy thing..
IMO and experience with it, the E9000 is excellent and worth the price. I paid around $60 USD last year. I have used it twice on stained cabinets and recently on old trim that had oil base paint on it. Neither cabs projects were oak, so no input on if it fills. Light...light scuff with 320. I used a turbine HVLP with 1.8 cap. I have not used their catalyst. Thinned per Envirolak's specs for turbine.
It bonds, it covers, dries with a slight sheen...almost looks like a finish coat..It sands well but not as powdery as others.. It has a unique odor...think vinegar+Elmer's glue. It is not tintable. In a perfect world, I would like to end up with an AAA type hookup.
The E200 is excellent as well. I like the dry time, leveling and i would definitely choose it for dark colors. If i remember correctly, it sands more powdery than the E9000. At this time, I feel it brushes better than it rolls. I mini rolled sides of cab boxes and large sides of fridge(it was fine on faceframe) with 1/4 (5-6mm?) and just didn't like it..its like it didn't spread well on the larger areas..like enough to consider spraying larger surfaces. It does have "sag potential". I used the 20 sheen and consider it a low satin. Do not use a high elastomeric caulk (big stretch, Tower Tech 2 etc.) the E200 will hairline crack. I use a modified acrylic sealant by AllPro called Quick2Coat.
The dealer I get it from says the E200 will take the Next Gen tints..might not have said that correctly, but my point, is that one doesn't have to use Envirolak's tints exclusively...don't feel like you need to buy their colorants.
Spraying in general has been a part of my recent learning curve so I'm sure there are others with more qualified input. I don't have comparison input to Command or Advance and my pics are not up close ones.
I think you're gonna love both and hope to read what your experience has been. Hope more folks share their experience too.
Cheers
